Ping Pong Parachute B/C

PPP world record!! 20+ minutes!!!

I was dying to see how high my rocket would go at 65 psi. So I took it out to the football field after testing. It was really windy so I took a back up parachute and loaded it on. Set the pressure to 65 and let it rip. Rocket went up, deployed the chute, then it crumpled a bit in the wind and started dropping. Suddenly it opened fully and looked beautiful! Wind was blowing and it was drifting across the field and past the bleachers!. Then I realized, it was going UP!! It kept rising and blowing off in the distance like a Chinese lantern. Realizing I was not going to retrieve it soon, I packed everything into the car and started chasing it. I drove for about 15 min and lost sight of it completely. Gone!

Words cannot express how hard I'm laughing rn

I agree. That is the most scientific prediction in the world.

Is aluminized mylar a prohibited metal?

Technically, it's prohibited.

It is against the rules but I saw a team at SOUP with a parachute made of aluminized mylar but ig the ES didn't catch it lmao

i guess it depends on the ES but it's still illegal

I tried this out too, you can find my predictions here.

Wow, those are some bold predictions right there! Maybe switch 1st and 2nd place though?

It's honestly a toss-up. They've both been doing really great this year.

I actually did this event as a trial two years ago and we were only allowed to load to 40psi. I found that this gets it up pretty high and we got about 13-15 second launches. I'm hoping to get 30ish second launches this year! good luck everyone!

I am helping to coach this event and we are not getting over 5 seconds. Can you provide any tips? What is more important the bottle or the parachute?

Generally, my first priority would be to get your rocket to a point where it deploys consistlently, 100% of the time regardless of the room height or psi used. Then, you can work on optimizing your parachute to get the slowest descent rate possible.

What design are you using right now?
