Mentos Boy in a Box – New Twist on Mentos Geyser Tube

If you’ve followed us over the years, you know that NAEYC (the National Association for the Education of Young Children) is the first teacher conference where we introduced the famous Mentos Geyser Experiment. In 2006, we launched 700 geysers in the open air on the trade show floor. The Geyser Chamber made its debut in 2007 to show how the geyser shoots 30 feet in the air. This year it’s Boy in a Box… a clear plastic container measuring 4′ x 4′ x 7′ where geysers fly at the rate of 30 per hour (watch the streaming video). It’s easy to find the Steve Spangler Science booth in the NAEYC exhibit hall – just listen for the screams followed by applause.
