DIY Thermochromic Slime | Easy Colour-Changing Putty | Best Recipe for Stretchy Slime

Adding thermochromic pigment to slime adds a bit more interest and fun for kids, and I demonstrate it in this video by adding the colour-changing powder to the best slime recipe I know.

The recipe is the most ‘foolproof’ recipe I’ve found (and I’ve tried a few!) and creates really stretchy slime.

The thermochromic powder I used ended up requiring hot water to activate it, which isn’t the best for young children, so try and find pigment that changes at a temperature that’s low enough for warm hands to reach. It’s not the cheapest thing to buy, but a little goes a long way, and the pigment produces a vivid colour of slime too.

I hope you enjoy following along with the recipe, and thanks for watching 🙂
