Unspillable bubble liquid bottle

thingiverse

I made this as I am tired of my kids spilling all their bubble liquid within the first 5 minutes of opening the bottle. You will need a sheet of silicone, only a small piece, large enough to cut out a circle that will cover the inside of the lid with the slit. The silicone sheet I used is 0.75mm thick. I would not recommend sticking it to your lid using superglue, this is far too brittle and may come off. Instead, I would recommend using silicone glue.This design is not without problems:You require 2 lids, one with the wand attached which is also used for storage, one with the silicone sheet for preventing spills.If the simple stick wand is rotated while inside the bottle, a small child may have difficulty getting it out again. There is a wide version of the wand that solves this problem.Let me know if you find any other problems with the bottle or if you would recommend any improvements.
