Our science experiment this week is growing borax crystals on pipe cleaners shaped like snowflakes. It was a lot of work, but the kids love watching them grow (so do I!). I forgot how fast the borax crystals form, and by the time I was finished with the last batch the first batch already had crystals forming on the top. I took the basic recipe from here which I found on Pinterest (of course!). I made most of the pipe cleaner snowflakes after having two girls try it, and the results weren't what I expected. We also chose to add blue food coloring to make it even more fun! Anyways, here are the pictures.
We didn't have enough mason jars (read: we didn't want to wash them all) so we used large clear plastic cups instead. I wasn't sure how they would do with the boiling water, but they held up great since I let the water cool a little before pouring it in.
After only a few hours the crystals are growing!
