 | WoOt! What fun! We'd seen this experiment done on the tele, and gave it a go at home - but we could never get the Mentos in quickly enough, so it was more an "overflow" than an explosive geyser. This tube makes it so darn simple, and it shot softdrink higher than the roof of my highset house. The kids loved it! Bugger the kids...I loved it! Now I have to send it off to school for show and share...hope the teacher heeds my warning to do it outside..... Julie Boxsell, Aitkenvale, QLD
