Do you guys remember these ?
One of the best things about Bali when you are a kid.
Although I have a vague memory (and I can smell the fumes) that someone told me they are fairly toxic, they are pretty fun for a one off occasion.
If you put two or three tubes of the glue stuff together you can get huge giant bubbles.
These little boxes of fun are available at all of the little tiny shops and in the markets for about 10,000 rupiah.
Most suitable from about 6 years and up I think (for blowing the bubbles anyway).
