I believe a couple "well know in the US" pilots did zip lock baggies.......
They would put an eaten apple core in the bag before tossing.....sorta like an apple core and "apple juice" going out....issue is.....DON'T zip it closed going out.....the drop flutters most liquid (thus energy) on the way down....
A quart or so dropping a long way has a ton of kinetic energy.

I used to buy Gatorade by the quart......I picked a reddish color drink.....easier to figure out "drink vs. pee" after a flight.....
Same for long road trips......LOL......
