Demo Tank
This narrow tank is perfect for demonstrating float and sink; pouring gas from one container to another; and growing Alligator Gro-Beasts. Its narrow width minimizes the amount of water; while its clear sides maximizes visibility. This tank was originally designed and produced by Ron Perkins in 1984 as part of the elementary science teaching program taught by his AP Chemistry students at Greenwich High School, Greenwich, CT. Approx 40cm x 25cm x 12cm (~15.5" x 10" x 4.5").
