Heat sensor paint - see how hot your husband really is

I sent the link for this heat-sensor paint to my husband via Messenger, and the comment came right back: 'It'd change colour every time I walked past!'. Because, yes, I am blessed with a husband with a high body temperature, which works like a dream when it comes to getting babies off to sleep, I can tell you. It also means I can tell people, 'My husband's hot!' and always mean it.

I'm tempted to see if he really could have a remote effect on this paint, one of a fun line from Crayola that allows you to see your own handprint appear and then fade, due to its heat-sensor properties. It's quite possible he could stand in the garden and watch it change colour.

Other options in the Crayola range include the slightly less unusual magnetic and chalkboard paints, and a mother-of-pearl topcoat that is definitely worth a gander. Then there's glitter paint, glow-in-the-dark paint, and a very practical scrubbable paint. If, like me, you thought Crayola only did crayons, you'll be pleasantly surprised.
