It’s tough to really demonstrate the Mentos Geyser Tube in an exhibit hall filled with teahcers… until we created the Mentos Geyser Chamber. It’s a plastic box that measures 4 feet square and 7 feet tall. It’s the perfect enclosure to launch off a few hundred Mentos Diet Coke geysers. The only other thing you need is someone to stand inside the box for a few hours. Most of the time, Drew Vriesman is an undergraduate at the University of Colorado, Boulder, studying marketing. But when he puts on his intern hat at Steve Spangler Science, he’s never quite sure what to expect. Drew Vriesman and Taylor Marsh took turns launching geysers at the NAEYC 2008 conference in Dallas. Combined they launched 700 erupting Diet Coke geysers using over 4,000 MENTOS® Chewy Mints. The interns spent about 20 hours in the Geyser Box over three days and entertained (or amused) about 15,000 teachers who stopped by the Steve Spangler Science booth.
