An Essential Piece for any Young Scientist Lab!
Anatomy science toy for kids
Every mad scientist has a large specimen lab jar filled with body parts – a severed hand, a lopped off ear, a big fat nose, and a pickled brain – floating in a jar filled with water. The best part of all is that these body parts start off small and get bigger the longer they stay in the water until they reach their maximum size.
How big do they grow?
Each body part starts out about 5 cm (2 in) in length and grows to human proportions… or a little bigger. The body parts should reach their maximum size after 7 days of “pickling” in water. You’ll also receive a one gallon size wide-mouth specimen lab jar made out of clear plastic – perfect to hold your young scientist body parts.
How does it work?
Growing body parts are made using two different polymers: a hydrophilic superabsorbent polymer and a hydrophobic polymer. The hydrophilic polymer is a super absorber and is similar to the polymer found in baby diapers.
