I use the geysers with my students. The first few times the launcher was used it worked great. After that, soda came out of the pin holes on the side and out of the top (the plastic shield didn't not prevent soda from escaping from the pin holes.). Since soda escaped from the sides, the geyser didn't get as big and you got wet.
Greater geyser displays ahead for the students! We contacted the manufacturer about replacing the defective geyser tubes.
