how would i build a catapult using

Question

35 popsicle sticks
2 ft of duct tape
2 straws
2 rubber bands
2 plastic spoons

1 posterboard base

Answer 1

To build a catapult using the materials you have, follow these steps:

1. Lay the posterboard base on a flat surface. This will serve as the foundation for your catapult.

2. Take 8 popsicle sticks and arrange them side by side. Use the duct tape to secure them together, forming a rectangular shape. This will become the base of your catapult.

3. Take 4 popsicle sticks and tape them together in a triangular shape to create the support structure for the catapult arm. Repeat this step with the remaining 4 popsicle sticks to create a second triangular support structure.

4. Attach one end of each triangular support structure to either side of the rectangular base, forming an upside-down "V" shape.

5. Take one of the straws and align it horizontally across the top of the triangular support structures. Tape it securely to each support. This straw will serve as the guide for the catapult arm.

6. Place one of the spoons on the end of the straw that extends beyond the triangular support structure. Use a rubber band to secure the spoon onto the straw. Make sure it is tight enough to hold the spoon in place, but loose enough for it to be able to move freely.

7. Attach the second straw to the opposite side of the catapult arm structure, right below the first straw. This straw will serve as the pivot point for the catapult arm.

8. Take the second spoon and attach it to the free end of the second straw using a rubber band. Again, ensure it is secure while allowing it to move freely.

9. To launch objects with your catapult, place them inside the spoon attached to the arm. Pull back on the arm and release to fling objects across the room.

Remember, safety should be a priority while launching objects with a catapult. Ensure that no one is in the trajectory of the launched object to prevent accidents or injuries.
