1. Popsicle sticks
2. Super Glue
3. Double-Sided Tape
4. Electrical Tape
5. Sharp Scissors or a Knife
6. Round Pencils (as an axle)
8. Any sort of counterweight. (I used coins – See step 10 on how to make a counter weight)
9. Any sort of Projectile (I used polo :P)
10. Eye Hooks
Build the base of the trebuchet using Popsicle sticks and stick them to each other using super glue as shown.
Fortify the base from the other side by sticking more Popsicle sticks. First line the top and the bottom edge with a popsicle stick each. Glue them firmly and wait till they dry. Then Do the same for the right and left sides. Repeat this layering until you have two layers. This will give the structure a firm base.
Create a structure as shown below. Do this by using a Popsicle stick and placing two other sticks at an angle on either side of this stick, then place another popsicle stick over it to fortify the pillar.
Repeat Step 3 and create a similar structure. These will act as pillars or columns to support the upper body (the axle) of the trebuchet.
First use super glue to join the pillars to the base. And let it dry for a while to strengthen the structure.
Then use washers and place them between the two pillars. One must make sure that the holes in the washers are big enough for the pencil to fit through. Use another Popsicle stick to fortify the two pillars together. Use double sided tape if necessary.
