Ping Pong Ball Projectile Launcher

In summary, the conversation discusses the materials allowed for a project involving building a ping-pong ball launcher. The materials include cardboard, paper towel tubes, popsicle sticks, rubber bands, paper clips, and tape/glue. The launcher must be able to launch a standard 38 mm ping-pong ball to long distances from a desk with a height of 76.5 cm. A helpful resource for building the launcher is provided.

Allowed materials:
-1 sheet of 8"x8" cardboard to be used as the base
-another sheet of 8"x8" cardboard (that may be cut)
-2 standard paper towel tubes
-10 standard popsicle sticks
-up to 10 rubber bands (maximum unstretched length is 10 cm)
-5 standard paper clips (max length 5 cm each)
- tape/glue**The projectile will be a standard, 38 mm, ping-pong ball and must be launched to long distances from a desk with a height of 76.5 cm (30 in)

I really need help with this please just give me some basic ideas on where to start or some guidelines! thank you!

1. How does a ping pong ball projectile launcher work?

A ping pong ball projectile launcher works by using compressed air to propel a ping pong ball at high speeds. The launcher typically has a chamber where the air is compressed and then released through a nozzle, launching the ball forward.

2. What materials are needed to build a ping pong ball projectile launcher?

The materials needed to build a ping pong ball projectile launcher include PVC pipes, a valve, a nozzle, an air compressor or pump, and a trigger mechanism. Optional materials may include wood for a base and decorations, as well as paint for customization.

3. How far can a ping pong ball projectile launcher shoot?

The distance a ping pong ball projectile launcher can shoot depends on the amount of air pressure used and the angle of the launcher. On average, a well-built launcher can shoot a ping pong ball up to 100 feet.

4. Is it safe to use a ping pong ball projectile launcher?

As with any projectile launcher, safety precautions should be taken when using a ping pong ball projectile launcher. It is important to wear eye protection and ensure that no one is in the path of the ball when it is launched. Additionally, the launcher should be constructed and operated carefully to prevent any accidents or malfunctions.

5. Can a ping pong ball projectile launcher be used for educational purposes?

Yes, a ping pong ball projectile launcher can be a great tool for educational purposes. It can be used to teach principles of physics, such as projectile motion and energy transfer. It can also be used for experiments and demonstrations in a classroom setting.
