Thames & Kosmos Molecule Beads Experiment Kit

My 12 year old spent a summer afternoon playing With the Molecule Beads kit. She was easily able to understand the directions for play on her own. She described this activity as entertaining. She would recommend it to a peer her age. There was plenty of leftover for another two or three times of play. Easy clean up, too.

My Granddaughter was soooo happy to receive this Molecule Beads set! She is inquisitive, curious and oh so ready to explore the scientific world of "plump and squishy polymer gel beads to demonstrate the molecular structure of plastics". The kit comes with red alginate liquid, yellow alginate liquid, 2 packets of calcium lactate powder, cup with lid, spatula, and a spoon. Also needed is a scissors, a plate, and water. It comes with 2 experiments. What happens is when the solution comes into contact with the calcium lactate, the liquid turns into a jelly-like solid ball. A giant molecular complex has formed, or what is known as a polymeric compound. Presto, you have created a giant molecule, or a plump and squishy polymer! My granddaughter looked in such awe at her creations! She also had fun jiggling it in front of her little sister! 5 Stars ***** for fun and learning! Ages 8 and up.
