Inner Peace - Tumbler

A physics tumbler for anyone trying to stay calm while life turns up the heat.

A meditating popcorn kernel has found inner peace at a spectacularly inconvenient moment. Real popcorn pops when heating builds pressure inside the kernel until its hull ruptures and its starchy interior expands. This one seems to have scheduled a breathing exercise instead.

20oz stainless steel tumbler with vacuum insulation and a clear push-on lid. Dishwasher safe.

Perfect for: science fans, popcorn lovers, and anyone whose day needs a pause. A playful gift for a teacher, student, or overworked friend.
