Anyone know how to build a catapult? The pack's Catapult Challenge is coming up in 6 weeks and each den needs to build one....must fit into a 3'x3'x3' box, no more than 3 bungee cords/silicon tubes and ammo will be navel oranges.
I must be nuts...

I remember that I built one when I was a scout, but I do not remember how I built it.

They were having the race in town, so my parents packed us all up and headed down to check it out. Being the 7 year old that I was, I wasn't much into staring at the top of the hill just waiting for the cars to come rolling down. Therefore I had my back to the road and was playing in the dirt. Next thing I know, i'm waking up in the hospital. The "GIRL" who was driving the car had a small head.( something you dont see every day) Anyway, since her head was so small, her helmet didnt fit right and kept falling down over her eyes. In case you dont know what these cars are like..its a small go kart kinda thing that goes downhill only. You need to be shoe-horned into them(kinda like D' in the focus) and cant move once your in. Your arms are tucked in, underneath and all you can do is steer. So of course halfway down the hill, her helmet falls down over her eyes, she veeres off the side of the road, and I was so nice to come between her and the nice shiny guard rail. As the car was veering off the road towards me, everyone ran away. My mom pushed the carriage with my little bro in it and tried to grab me at the same time. My arm slipped out of her hand and before she knew it, I was smashed into the guardrail, knocked out cold with blood pouring out of my head. Paramedics came and took me to the hospital. I got a bunch of stitches in my head and was bruised up pretty bad but I survived. The doctors said that if I was turned around watching the race, I most likely would've died. They said I would've seen it coming and tensed up my body, which would've caused a lot more damage. Since I wasnt looking, my body was limp at the time of impact. They said thats what saved me. I did however make the front page of the local newspaper, meet the whack a$$ girl that was driving the car and got her helmet and a T-shirt...LOL...If that was today, I'de be a very rich man.
And that my friends is why I dont like them damn soap box derby cars.

I am sorry for what happened to you and I am glad that you survived. I can understand why you would not like soap box racers to this day. My cubmobile went slow and cruised about, rather than get involved in any races. By the way for any of you who want to build a cubmobile for your kids, I think that you can still find the plans in the cub scout manual. (I know that you can find them in an older manual if you may have yours or can find one).
Brew back to you!

Mike150-
We need more specifics on the size- Does it need to fit in a 3' cube fully assembled, or do you just need to fit it in a 3' cube to truck it in to the site and then perhaps do some minor assembly on site?

I think that it needs to be fully assembled at that measurement. By the way, the one that I built was smaller than that, however, the scouting rules tend to be very stringent.

Google is your friend. Once you get your design, your biggest challenge will be finding and securing a source for your heavy duty rubber surgical tubing. This is what will make or break your venture. The stronger your rubber band, the more power you have.

Myth busters did a show on economy sized sling shots here while back. Might look and see if you can find it some where. They experimented with various materials for the sling. Including surgical tubing, but I belive they found military grade bungee cords to have the strongest tensil strength and the most memory resistance. (IE slung better and could pull them further and with more force before the ybroke than anything else they could think of that stretches.) You might need to make a trip to you local military surplus store to get some.

It was the Surgical Tubing that did the best. They got the most strength out of that, however, the military grade stuff came in second.

If you have a BitTorrent and want to then you can download that episode from here and watch it. It has a link to download a BitTorrent too.

I thought that they ended up using the military grade bungee.
Surgical tubing is definatly cool too. We made a 3 man water cannon to launch water balloons a few years ago out of surgical tubing and 200 yards shots were very easy. I may download it and watch it again later.

They used the slingshot to launch the test dummy over 200 feet. (Buster if you haven't watched the show). They found that surgical had the highest tensile strength when they stretched it out. They figured that they needed 15 or 20 lengths of this stuff at 10 ft in length and that they needed to stretch it five times it's normal length to get the desired pull power to launch Buster over the border of Canada. They only got a little over 200 ft, which was not enough and they busted the myth that people build these things to launch people over the border.
To mikef150,
good luck and good launching.

I think there's going to be a few late nights in the basement working on this over the next 2-3 weeks...
