Air Trajectory B/C

[Phys1cs]

We melted lead into a soda can. Works nicely, but was relatively difficult. I believe our AP Chem teacher supervised the whole thing which took place in a fume hood (lead is poisonous). An easier solution is using dumbbell weights.

We're just dropping a standard 500g circular weight. Like the ones you would use in a physics class

And you are able to reach the full 8 meters?

Yes, we're dropping from less than a foot above our air chamber and our ball goes almost 40 feet.

That's amazing!
Please elaborate! Whats your setup?

We've just got a kickball and a barrel in it.

Does anyone know if electronic devices are allowed, such as a small fan?

Per Rule 3h, "Electrical components are not allowed. as part of the device or trigger"

How do you fill your kickball up? What kind of ball do you use?

We just fill it with air...? It's your standard grade school kickball, like what you play 4 square with.

I meant as a projectile. Also, I meant HOW do you fill it with air. I use another kickball, but I'm curious to see what you use.

Are we allowed to use metal in our trebuchet? i.e. lumber screws

Yes, there isn't a rule that seems to prohibit them, as long as they are used safely. Calling your device a trebuchet continues to worry me as a traditional trebuchet does not use air to launch a projectile...
