Pack of five 15ml plastic test tubes with plastic stoppers. These transparent tubes come with screw-cap lids as well as rubber stoppers. Double the fun! Use them to mix a small amount of water and 1/4 of an alka seltzer tablet, then stand back and watch the gas build-up pop the stopper. This chemical reaction really makes the stopper fly! Tubes have a flat-bottom and are 1.5cm in diameter, 9.5cm high.

WARNING: CHOKING HAZARD Small parts. Not for children under 3 years.

CAUTION: When used as suggested, the rubber stopper acts like a projectile. Point away from faces, people and fragile objects.
