Learn to create an enormous geyser by combining Mentos with soda! The eruption is amazing -- up to 25' high -- and so is the learning if you consider the science just beneath the surface. Interchangeable caps fit on the Geyser Tube to allow various types of sprays: a single spray; a long, rectangular spray; a cross; and a 3-hole spray. Comes with a roll of Mentos, but you can try other activators to see what works best. After all, experimenting is all part of the science!
