Marbles are pretty cool, but did you know you can make them even more fascinating? You can, and it’s actually quite simple. It’s also a great little science experiment about what happens when materials expand and contract with temperature changes.
Watch the video below for the tutorial:
You can try this with marbles of any color and design and see what kind of cool results you get. In the end, they make for a great centerpiece!
And remember, when handling glass, always exercise caution. The marbles can shatter from this process, so be careful and keep your face away from the orbs when they’re popping.
