This is how I think I might be able to build a catapult(I haven’t tried it out yet).

You will need...

popsicle sticks

hot glue gun & hot glue

toilet paper roll

rubber band(very stretchy!)

regular, smooth stick

small, paper ball

Instructions

   1. Use the popsicle sticks and hot glue gun to glue together a triangle. On the bottom of the triangle, make an extra half stick poke out on both sides behind the triangle.Glue on two more popsicle sticks to the ends of the half sticks poking out. Make them face away from you so that the triangle sort of stands up. Make sure they are both on the same side, not one facing you and one facing away.

    2. Repeat step 1 to the part where you make the extra half stick poke out of the and of the triangle. DON’T follow anymore instructions from step 1.

    3. Glue the two triangles together, the two sticks facing away from you in step 1 connecting with the half sticks poking out of the triangle in step 2. You now have the base.

    4. Punch a hole in the top of both triangles where two popsicle sticks meet and in a separate popsicle stick. Put the regular stick through the popsicle stick with the hole through the middle. Hot glue in the regular stick through the holes in the base of the catapult. Make sure you DON’T hot glue the popsicle stick with the hole to the regular stick. DO hot glue the regular stick to the two triangles.

    5. Snap a few popsicle sticks into fourths and glue them to one of the ends of the popsicle stick swinging in the middle. Cut the toilet paper roll into a small sliver(not too big or not too small). Glue the sliver onto the fourths-of-a-popsicle-stick.

     6. Take the rubber band and glue it to the other end of the popsicle stick without the sliver of toilet paper roll. Glue another bit of the rubber band to the bit of popsicle stick underneath. Put the small paper ball in the sliver of toilet paper roll. Bravo! A catapult!

How To Use It

Push up the bit of popsicle stick with the rubber band attatched. Let go! The bit of popsicle stick that you were pushing up slams down on the popsicle stick on the bottom and the other bit of of popsicle stick with the sliver of toilet paper roll flies up, hopefully launching the paper ball.
