* Pictures of our Catapult *
Alright so hi guys.
Now I'm going to talk to you about the material used for our catapult.
So the material used for our catapult are cardboard, wooden stick, plastic spoon, a ball point pin (for the lock), a masking tape to hold the things down, and rubber band over here as our firing mechanism.
So the ball over here is made out of newspaper and inside there is actually spring and is taped up together by scotch tape
So I will be talking about the firing mechanism of the catapult over here the rubber band gives the plastic spoon torsion so it's able to be pulled down and released the wooden chopstick over here gives the rotation for the plastic spoon
The safety pin over here provides the locking for the mechanism and to release, just pull it backwards.
The chopstick that is through the plastic spoon over here provides a support. So that the projectile would be placed in the accurate position when firing.
To use the projectile. Push the spoon down and slide the pin in. Afterwards place the projection on the projectile seat. And fire it forward.
Thanks for watching.
