Yikes! I would not expect that to happen.

If you want to have some organic chemistry fun.
Grab a Champaign bottle, some standard latex balloons, powdered drain-o, and aluminum foil.
You can make flammable balloons.
(Same chemical reaction)
I wouldn't expect dish detergent to have enough caustic stuff to eat aluminum, though.
Given enough time
I was also surprised. At first we thought I had just overfilled it by a lot. It was a few weks later when it was time to refill that we found the hole.
Thanks for the explanation and the suggested science experiment. 🤓
If you can find timed cannon fuse, you can float the balloons over other peoples property and have even more fun.😆
