Rainbow Rolling Pin
Probably the easiest and simplest Instructable ever, but it's kind of ethereal pretty. It makes me smile when I see it because it really looks like blobs of light. The beads are translucent and almost transparent around the edges.
It takes less than 5 minutes, if that. :D
Find an Alcoholic.
Once you have found your alcoholic, grab a rolling pin-like bottle from their stash. If it's not empty, talk to them about the good ole days.
Drop a few of the water beads into the bottle, fill it with water, and cork it back up. I just happened to fill mine with exactly enough to make the beads immobile. They kind of have a cellular structure being pushed up all together.
Wait a day and you have rainbow blobs in a bottle.
Rainbow in a Bottle.
Make it. It's soooooo pretty. :D
I highly doubt it will win the rainbow contest because other Instructables are so awesome, but I thought it was worth grouping in the contest, if anything.
