Flubber is a fun and playful experiment that kids will never stop loving. This experiment will introduce students to non-Newtonian fluids. Flubber is neither a true liquid nor a true solid. It can be picked up like a solid, but it takes the shape of the container it is in just like a liquid does. Students can observe how two true liquids can make a non-Newtonian fluid and depending on the age group, students can dive deeper into the chemical properties behind this reaction. One thing is for sure; no matter the age group Flubber is always fun to play with.
