Instant Worms: School Lab Pack

Product Description

There's hardly a better way to get your class involved and intrigued in polymer science. Students simply squirt one liquid into the other using the included syringes and long slimey polymer worms are created instantly. This is a simple but fun chemical activity.

Contents: The School Lab Pack is packed for 20 students. Three containers with worm builder powder; worm medium powder; plastic cups (32); sticks (20); syringes (10); instructions and science info.

Please indicate above if you require the complete pack or only the chemical re-fill pack.  
The instructions and MSDS information is provided below. (The pack uses a small quantity of calcium chloride that is classified 'hazardous' when in the solid powder form. Once this is made up by the teacher in a solution, there is no irritation hazard to the students as the concentration is extremely low.)
