Step 1:

What you need:

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)
7. Washers
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
<p>My daughter made this for a school project but the &quot;bag&quot; is hitting the base. Do you know what could be causing this?</p>
How far do you think it'd throw stuff with the sling?
With this, I managed around 5 - 8 meters.
<p>How many popstickil sticks do I need</p>
is anyone here because they have to do this for a social studies project
I'm also gonna do it for my science fair project, great instructions
<p>Sounds like a sweet idea! I have a school project and am going to use this design probably.</p>
<p>thx ill that as a idea</p>
how far does it throw?<br>
Depends on the counterweight and the weight of the projectile itself. , mine threw about 10 meters.
<p>I have to throw throw my clay projectile over a few decametres how an i adjust it so it can go further?</p>
Fun! I love how you did this with popsicle sticks!
<p>How do i launch the projectile?</p>
I built it but the projectile just rolls out of the basket and lands half a meter behind me.
I faced that problem in the start too. So I put a weight onto the trebuchet so that it was sturdy enough. And I used smaller projectiles.
Awesome. What are eye hooks? Do you mean screw eyes?
Yeah Screw Eyes. They are called Eye Hooks here in Pakistan. Please rate this Instructable and follow me if you liked it :)
Could you add a picture of the screw eye you used?
Hey sorry. I went on the wrong note last time. I actually used washers. Not screw eyes. Sorry for the mistake there.
Washers? I know you used that to attach the axle, but what did you use to attach the counterweight?
Yeah you can use screw eyes there. But I didn't use them in my model. Instead I used just some string to attach the counterweight. In Singapore on the other hand they super glued the screw part to the trebuchet and the eye part was used to cling onto the counterweight.
oh i get it now. Thank you.
Rated 5 stars and i'm following you as well:)
If you want it to throw farther modify it so the counter weight goes under the pivot point and use a sling for the pouch.
Interesting. Thank You for the tip. I will consider it. :) Follow me if you liked this Instructable
