Potion Bottle Bubble String Lights: Decorate Your Tree With Chemistry

Apparently, decorating Christmas trees with little vials of methyl chloride was extremely popular in the 50s and 60s. Because methyl chloride has a low boiling point, a small bulb can generate enough heat to produce bubbles inside the vial, creating a mesmerizing effect. These "bubble lights" were a little before my time, but I can certainly appreciate the idea of a potentially dangerous but decorative chemistry experiment being repurposed for the needs of a modern, super nerdy Christmas tree. Enter potion bottle bubble string lights.

Its actually a brilliant idea. A string of potion bottles bubbling away would be the perfect anchor for a gaming-themed tree. They can be ordered here for $24.99 each. Each string only contains seven potion bottles, so putting together enough to decorate an entire tree might be an expensive undertaking. Throwing some of these D20 string lights into the mix might be a good idea. The complete list of specs for the potion bottle bubble lights is available below.
