I like the concept a lot, and I came up with a way to reset it without having to dump and refill
(using a big syringe to force air into the center chamber). However, in spite of its initial
promise, I immediately noticed a leak. The outer wall leaks approximately 10 drops of liquid per
minute, so the prop can’t be set up in advance without leaking all over the place. And it isn’t
something you can set up on the fly either.
I tried patching the leak with super glue —
didn’t work. And it would cost almost as much as the prop itself to ship it back for a refund, so
unfortunately this item is bound for the recycling bin. Bummer, I was really looking forward to
adding this to a milk in lightbulb routine.
