What I initially thought of as a brilliantly executed prank turned out to be an impressive example of thermochromism and heat-sensitive paint. Thermochromism is the property of certain materials to change their colour in response to a change in temperature.
Experience thermochromism! With this magic mug Dragon Ball by House of Spells, bring up the energy halo of Vegeta and call the dragon Shenron by pouring a hot beverage in the mug. The Design changes when you pour hot liquid. Unfortunately, not suitable for microwaves and dishwashers.
