I Need To Build A Small Catapult For My Daughter Maybe Using Items From Home. What Is The Best Way To Do It And What Can I Use?

Use wood and glue nails

Wood

Maybe use rubber bands, and a plastic spoon? My son has to make one and thats what I'm doing.

Go on www.makeyourowncatapult.com It really works...I had to make a castle catapult and I went on this site =]

This design for a catapult is great. It only uses toothpicks, tape and bottlecaps. Hopefully, you have some around.
You need three bottle caps, some clear sticky tape and two toothpicks that are about two or three inches long.

First, create a fulcrum. Tape two bottle caps together with the insides facing each other.

Then make the lever by taping the ends of the two toothpicks together. Tape the third bottle cap on to the end of one of the toothpicks. The inside of the cap should face away from the toothpick.

Next, attach the lever to the fulcrum. Tape the middle of the toothpick that is farthest away from the cap on the lever to the curved edge of the fulcrum.

Load the cap with a small object. Try a marble or crumpled up piece of paper. Press down on the far toothpick to launch the catapult. Perhaps your next project should be a toothpick fortress!

I do not know but maybe you can use popsicle stix and rubber bands. But you are on your own buddy.
