Mentos Geyser Tube. So you’ve been aching to recreate the Mentos and soda fountain gag, haven’t you? Ever since you saw that fabulous video? Well now here’s your chance. OK, so maybe it won’t get you a number one rating on YouTube, but you’ve got to start somewhere, haven’t you? £4.95.
Simply load the Mentos mints in this screw-on transparent tube, lock it on your plastic pop bottle (any fizzy drink will do but diet stuff works best) and pull the pin. Oh yes, and run for it. Because the moment the mints hit the liquid, a powerful soda geyser erupts from the top with enough pressure to reach 30ft – yes, 30ft! And thanks to this ingenious little gizmo you’ll get a perfect launch every time without getting drenched.
