When I saw this jar of 'water marbles' on Pinterest, I was of course intrigued and desperately wanted to make my own. The Pinterest picture incorrectly says that they can be made with 'just a few simple kitchen ingredients'. I never looked to see what they were because when I investigated this craft, a lot of people said all they ended up with was a big fat mess in their kitchen and it didn't work. Someone else said that these colourful water marbles are made from a polymer bead that expands in water, and the kit can be bought online.
I found them on Amazon.com for $5!!!!
They start out as tiny little opaque or clear beads.
Here they are after being put in water.
About an hour later. The clear marbles all but disappear.
And after another hour
Here they are after being submerged all night long!
They are sooo cool! Very firm to the touch, slippery, rubbery and they bounce!
I'm not sure what happens after they dehydrate.
As of today, they have only shrunk a little bit!
