I couldn’t believe my eyes today when Dad unpacked a small tube and a small straw and told me that we’re gonna inflate some balloons now. Then he opened the tube and emptied it. It contained a sticky, silicone like mass. He stuck the straw into that mass and started blowing.
I almost fell off my chair when, out of that mass, a big bubble started forming. 😯
In the end, we had a lot of fun with these things. Dad told me that he used them as a kid but as far as he knows, they are forbidden in Europe because they were toxic or too dangerous for kids or something. 😉
