This Instructable will show you how to make a giant slingshot.

PS I am entering this in the Alchemy Goods Inner Tube Reuse Contest!

Step 1: Materials

You will need a inner tube (any as long as it is still holding together, it's ok if it is punctured)
a frame (giant Y log, two trees ect.)
a bucket or plastic bowl
Just curious... but which of those images did you actually create?
on step 1 I created the second one and step 2. The first picture (in the intro) was of my cousins slingshot.
This is your cousin's? http://www.roadsideamerica.com/tip/12314
The following text has been censored. My cousin emailed me saying that he and his friends built that! He lives so far away so I rarely see him. When i do see him he is dead (figuratively)!
What was your cousin's name?
I am not sure if he will want me to say this so I'll pm you after you reply to this comment.
i think it's important that you mention safety hazards in building this. with so much tension in the tube, the frame is pretty likely to be uprooted and fly backward. even one of the connections of the tube to the frame can pop off and hit you. and, as with any siege, engine, you have to make sure that no one is anywhere NEAR where you're launching. <br>i think you should mention these in the actual instructable and not just in the comments, especially about making a very strong, very secure frame. include instructions on how to do it safely, not just saying to get one.<br>other than that, very good idea and seriously, it needs a video. it's cruel to post something like this on the internet and not include a video.
About the safety hazards ill do that, but that is what the disclaimer is for. But seriously I'll talk about the safety hazards. I did say to never aim at any living thing. But about the video i am currently trying to find time to do that.
If its your 'cousins' catapult, how are you trying to find time to make a video when you rarely see him.
The original was given to me from my cousin and he said it was his but it was not. However I did build my own but since my camera stinks and I have to take pictures from my computer using a webcam which I cannot move because it is one of those old computers that take up a lot of space and are really heavy. I might build a pinhole camera to take he picture.
I'm going to put one of these bad boys up on my workplace roof!
Nice get a picture when your done.

to late...<br>my brother was hit in the face launching water balloons. He did not get hurt (or did he).
My early-teen daughter got hit in the face with a water balloon. After a couple months of eyedrops and a bunch of opthalmologist visits, you couldn't see the little pool of blood at the bottom of her iris anymore. (mind you, this was paranoid and precautionary; there were never any noticeable vision problems. But that &quot;you'll poke your eye out&quot; cliche is only amusing when it hasn't come close to happening.)<br><br>there are rumors that the amazing-race clip is a fake (waterballoon instead of a watermellon, etc) I think that even so, she was pretty lucky not to have been more seriously hurt...<br>
I think it was fake. A watermelon at that speed would at least cause a bloody nose not just a headache.
Can you post a video to show the result? Could be spectacular!
good idea. I should find some time for that :-) .
Yes! This requires video!
