How to Make a Projectile Launcher

1. Step 1: Supplies. 1 pencil 1 rubber band 1 binder clip a lot of paper.
2. Step 2: Preparing the Clip. tie the rubber band around the binder clip.
3. Step 3: Put the Binder Clip on the Pencil. open the two metal prongs and slide the clip on the pencil.
4. Step 4: Make Ammo.
5. Step 5: How to Shoot.

What is the size of a ping pong ball?

Since the diameter of a ping-pong ball is about 38 mm, this leaves a little over 1 mm clearance for the ping-pong ball in the tube.

### How does a projectile launcher work?

Launcher The Projectile Launcher is used to investigate important concepts in two- dimensional kinematics. A steel ball placed in the launch barrel can be projected for different launch velocities and launch angles. Upon setting the desired angle and range, the hand pump is then used to pressurize the system.

How do you make a unique catapult?

Simple craft stick catapult:

1. Stack five craft sticks together and wrap a rubber band around each end.
2. Stack two craft sticks and wrap a rubber band around only one end.
3. Slide the five sticks in-between the two sticks, as shown.
4. Wrap a rubber band where the two sections meet to hold the catapult together.

## Why does a ping pong ball stay in a funnel?

Because fast moving air is at a lower pressure than slow moving air, the ball gets trapped in an area of low pressure. The air further away from the ball is exerting pressure on the ball to keep it stuck inside the funnel when you blow.

Which has greater pressure inside or outside the ping pong ball?

Bernoulli observed that fast moving air creates an area of low pressure. The low pressure between the ping pong balls allows the higher pressure outside of the balls to push them towards each other.
