Bob wrote:How To Build an Evangelistic Bible Quiz Booth
You need 6 basic things:
flyers to hand out
a willing congregation.
Duct tape. (Thanks to the Red-Green show, who learned the virtues of Duct tape from me and made a great TV show out of it! The Red-Green show started in Hamilton! Maybe Red-Green did our Bible quiz one summer long ago and thought it would make a great idea for a TV show?)
Here is the finished booth!
I use a 10 x 12 foot tent that is open air concept. Go to a specialty tent store and buy one that is high so that you can walk right under each corner without ducking. You do not need a tent with any sides. Notice I position the button board at the just inside the very back (behind) of the tent. I stand outside the tent facing those taking the quiz. Pictured below is a 3/4 inch x 12 foot rebar that supports the sign. We drill a 7/8 inch X 18 inch hole in the ground with a drill.(see below) Then we duct tape the tent leg to the rebar.
We get a specific rider from our insurance company for a blanket $2 million liability endorsement for each fair. Think safety! The duct tape secures the aluminum tent leg to the rebar so that it will not fly away in high winds. Tents are like parachutes and very dangerous when they fly through the air! Use lots of duct tape (10 wraps) to tape the tent leg to the rebar. Below is the leg at the rear of the button board. Notice that we can tie the sign rope to the bottom of the tent leg for stability in winds. So the rebar holds the whole thing together. The Duct tape holds the tent to the rebar and the rope holds the sign to the rebar. The rebar is doing all the holding work! Pictured below is a 1/2 inch x 2 foot rebar. We hammered into the gound.
Then you can buy a steel "u-clamp" and bend it to fasten the tent leg to the button board.
We use two kinds of signs. Four 1 x 2 foot double sided "Bible quiz" signs. A banner sign that is 2 x 12 feet made from which plastic vinyl with vinyl letters. This is the main sign that is over the booth.
Signs: If the booth is on earth:
Buy two 3/4 inch x 12 foot lengths of rebar. These are the vertical supports for the sign. But an 18 inch long wood auger drill that is 7/8 inch in diameter. You may need to grind the end down so that it will fit in your cordless 3/8 inch drill. Grind it down with a continuous slow spinning motion so it remains circular, otherwise it will wobble when you actually drill with it. You then drill an 18 inch pilot hole into which the 3/4 inch rebars will fit into. Pictured below is the drill we use for the rebar for the sign. It is a pilot hole that the rebar just dropped down into for support. But you still need front and back support ropes for each side!
Make sure you buy four 1/2 inch steel "rebar" stakes that are at least 2 feet long. Drive them into the ground with a large mallet Buy 2 packages of 50 foot soft white nylon packing rope. Fold the rope in half and tie the half way point at the top of the 12 foot rebar. This rope is your front and rear "guy wires". On the front wires hammer a 1/2 inch x 2 foot rebar into the ground, tie the rope and put a double sided "bible quiz" sign on top. Make sure you duck tape the top sharp side of the rebar before you attach this small sign. Pictured below is a 1/2 x 2 foot rebar about 10 feet out in front of the tent. This is the support for the front guy wire for the large over head sign.
After duck taping the top of the rebar like a hockey stick but end so no one can impale themselves by falling on it, put a "bible quiz" sign on the rebar. This sign is two pieces of "plastic corrugated cardboard". Tape the sides together and put the rebar inside or between the two signs. More tape on the top holds the sign on the rebar. Then you can tie the sign rope to the bottom for wind support.
Buy two 2 inch x 2 inch x12 foot AND two 2x2 x 2 foot spruce lumber. Take the two 2 foot peices and attach them to the top of the 3/4 inch x 12 foot rebar using automotive "U-bolts". The round portion of the u-bolt is next to the rebar and the flat portion is against the wood. Tighten the two bolts down and use duck tape to protect the sharp edges from cutting the vinyl sign. (You never need to remove the duct tape wrapped over the u-bolts.)
At the top and bottom of the 2 foot pieces of wood, attach 4 "L-brackets" that are about 4 inches long. Use 1 inch X10 Robertson pan head wood screws to fasten them permanently to the 2 foot lumber. Use these screws to also attach the 2x2x12 foot lumber to the other side of the L-bracket to complete the square wooden frame on the 12 foot vertical rebar supports. Here is a close up of the corner assembly. Permanently duct tape the U-bolts after they are tightened with a wrench.
This makes the wooden frame that you fasten the vinyl sign to with a T-50 or T-18 staple gun as this child below is doing.
Staple the banner around the back of the wooden frame and drop into place! (Remember the two holes you drilled with th 7/8 inch x 18 inches auger into the ground?
When you are done the sign support you will have only two different components (four pieces): Two 12 foot rebars with 2 foot wood attached by U-bolts to the rebar and the L-brackets attached to the 2 foot lumber, with the rope. (these remain permanent units that you never take apart) AND Two 2x2x12 foot pieces of lumber. When you unload the truck, all you need is 8 screws to attach the 12 foot lumber to L-brackets on the 2 foot lumber! Pictured below are the components that never need to be taken apart. To build the sign support simply use 2 screws for each corner!
Wiring the Quiz board
The quiz board is actually two separate units. Each unit is 2 x 6 feet in size. They are fastened together with a clasp and screws.
Buy a 4 X 8 chunk of high gloss white shower board from a specialty plywood supply store. This stuff can be used as a white board with dry erasable markers. Cut out two 2x6 foot pieces.
Build a slanted frame out of 3/4 inch x plywood for the white top to rest upon.
Use a glue stick and paste a copy of the questions on the white board exactly where they will end up going. Mark out with dry erasable markers on the white board, where the buttons will go and the lights above each question pages.
Buy a 12 volt 7 AH dry cell rechargeable battery. (the same ones that are in every home or business alarm system box in the basement)
Buy the 20 lights and corresponding sockets from radio shack. Use 12 volt incandescent. Buy two cans of spray paint. Spray 10 with florescent green and 10 with florescent red. The red are the "wrong answer" and the greed are the "right answer" lights.
Make the templates like you see below and glue them to the board. Pre-drill the holes for the two light bulbs so when they are screwed into the socked the white board holds them in place. Here are four different examples of templates. When any button is pushed, either the green or red light will come on in side this template! Just use a glue stick.
Buy 50 red buttons. These are momentary contact mini buttons.($1 each). Find a drill that is exactly the right size for the button to push up through the white board from below and be fastened with the nut and washer that comes with each switch. Pre-mark the holes with a dry erasable marker. Make sure the questions are glued on first so you drill the holes exactly where they need to be.
Get a soldering gun and use light gauge wire. (AWG 22) I use standard telephone and strip off the outer casing so I get 4 different wires. Each wire then can be used individually. Soldier 8 inch leads onto the momentary contact buttons.
Use "b-connectors" or "chicklets" to make connections. (put the two or more wires in and squash with pliers.)
All the electric circuits are simple "series". The battery positive goes to one of the two 8 inch switch wires, which when pressed, the other switch wire sends power to one of the light leads, then the other light lead is wired back to the battery negative. It is best if you find someone in the congregation who has had some electrical experience to do the wiring. But in fact, anyone can do it!
Wire up the two button boards in parallel to one battery.
When all is working ok, remove the 8 paper questions off the two boards and use water to wash it down. After drying, print a colour set and use a glue stick to fasten the final questions to the board. I generally do this after the booth is set up.
Various types of questions:
For multiple choice questions you have a question with three answers. Only one is correct, two are wrong. Wire up the two wrong buttons so that whey they are pressed, the red "wrong" light turns on. Wire up the one right answer to light up the green correct light turns on.
This gospel preacher doesn’t realize that the two quiz boards are screwed together (see above) and he does not need to hold the two boards together with his arms.
Above is a multiple choice question. Below left is what the same 3 button multiple choice question looks like from underneath. Below right is a 10 button true or false question. The wiring is simple series circuits.
For true or false questions: you have a single theme like: True for false: Is it sin? Then you have 10 buttons. Each question is either true for false. If true, the green light turns on. If false, the red light turns on. Below is the "identify the sin" question that was very powerful.
Below is the fabulous "Is it a Bible quote" question. This question sends the "Billy Graham crowd" spinning away in confusion because they get almost every one wrong based upon the false doctrine of salvation by faith alone via the sinners prayer.
Time line questions: The time line uses smaller lights and I start by printing the time line and taping it to a piece of plywood and drilling the holes right through the paper. Then each button lights up a single light on the time line. This question has 10 buttons. When each button is pushed, it lights up a different light drilled into the time line. You can see the "first pope" button is pushed and 606 AD lights up on the time line. I use a smaller 12 volt light that comes with two 6 inch leads. The glass in the bulb is less than 1/4 inch in diameter. Chose a drill size that allows the bulb to slide into place then silicone them into place. Make sure the bulb is flush to the 1/2 inch plywood because people will push the bulbs and break them.
How to be saved conversion examples questions: This is a little more complex to build, because one button may turn on "believe or repentance or confession or baptism" or one button may turn on "believe AND baptism" or "believe AND repent AND baptism".
The last question lights up all four. So some buttons light up one light, two lights, three lights or four lights, depending on the Bible verse. Buy 20 1 watt diodes and put one in series of every conductor that runs from the button and the lights. For example, if a button turns on two lights, the circuit starts at the battery, goes to the button, then two separate wires to each separate light, then back to the battery. But two diodes on each conductor between the button and the light. Diodes are about $1 each. If you put the diode in backwards, it won’t light at all. Just reverse the polarity on the diode. If you don’t use diodes, all lights will light up every button you push.
Use either 2 white liquid gas lanterns at the top inside peak of the tent or two twin halogen lights on contractor tripods (500 watt bulbs in each light.) Point one at the sign and the other at the roof inside the tent.
Home Depot sells these. Make sure you buy the tallest and largest one they sell. (7 feet hight)
