Set 12 includes: Surface Tension (Kit 34) – Polymers (Kit 35) – Famous Scientists and Their Experiments (Kit 36)SLIME, SHRINKING PACKING PEANUTS, JUMPING PEPPER, AND BUBBLES. A foil boat gliding across the water, pepper jumping, and very large bubbles are all possible with the presence of surface tension. Diapers, slime, bouncy balls, and shrinking peanuts are created with polymers. This set is completed with recreating experiments of famous scientists. Make a Cartesian Diver, Galileo's Pendulum, and study Archimedes' and Bernoulli's Principles. Young Scientists will for sure be inspired by these famous scientists and maybe even become one themselves...
