Along with their Christmas card this year, my Grammy sent me this little zip lock full of beads.
I had absolutely no idea what they were - but they came with directions to stick into a liter of water. I figured that there was no way that tiny packet needed a liter of water, so I put them into a little mason jar full of water.
And lo and behold, they began to grow:
Until eventually, I had to dump them into a bigger container because they just kept growing!
These things are actually pretty cool! Once they've been exposed to water, they swell into these big glassy-type beads that are rather pretty and can be used for decoration. Anyway, I've never heard of them before now, so I thought I'd share.
