Those kids deserve to have their butts kicked.
On the subject of drops, many moons ago on halloween we had a pumpkin drop contest at the DZ at a private airport. The idea was to get out of the airplane holding the pumpkin, get the parachute open, descend to 2,000', and try to drop the pumpkin in a trash can identified with big orange panel markers. From there the jumper would proceed to a gravel "peas" area for a spot landing on a 3 cm electronic disc.
I foolishly brought a bigger pumpkin, which I carved, while others wisely brought small gourd-like pumpkins they could hold in one hand. I ended up having a total malfunction anyway, and got rid of the pumpkin for a reserve ride back down, but I sat on the ground and watched others do their thing. The funniest part of the day was watching someone spiraling down with the pumpkin in their mouth. He was holding it by the stem, and the stem broke off. I saw a little tiny dot move away from him, and someone yelled, and several folks started running. It hit about ten feet behind them, and sounded like a small grenade. One of them fell down and started screaming, "I'm hit, I'm hit," at which everyone else began laughing. Pumpkin shrapnel. I guess from 2,000', it hurts...they sure blow apart from that altitude when they impact.
For the record, if you're going to jump out of an airplane with a pumpkin, smaller is better.
