Science Experiments In A Tube

When CK was away in the US for training recently, I made him pack a box of Amazon stuff back. Although he couldn't bring back too much due the airport regulation (as he claimed), it was great to see him oblige once in a while and shop for kiddish stuff that he usually wouldn't buy.

He bought them a set of Be Amazing Lab-in-a-bag Test Tube Wonders. It consists of 5 test tubes with mini experiments in each one. We took out the Superabsorbent Crystals with colouring tablets and Growing Dino today. 

The crystals are actually gel that looks like crystals. The coloured water is absorbed slowly until it looks like a cluster of crystals. The kids were very excited and tried to keep watching it for some changes to be seen.

The Growing Dino absorbs water and grows bigger so Sophie will track its size over 3-4 days after we soak it in water for 24 hours. In theory it should grow bigger and bigger while it is in water and shrink back once out of the water. Thus, both experiments take time to work. And I have to leave it at the counter.
