A must have when working with heat
Review by Mandy
This is a must have when working with a heat source and test tubes. It keeps your childs hand far away enough to not get burned. I use it with lifepac science experiments. Works like a charm!
Review by Mark
These are very useful when working with the test tubes. Great price!
Simple but effective
Review by Duane
No bells or whistles...but then again it does it job simply and effectively. I bought two so each of my kids has one available for their experiments. I may need to buy another one since my son is pretty sure he can incorporate it into one of his Lego designs!!
