Common questions
Questions parents ask
What age is too young for color mixing?
The Mess Free Color Mixing Bag works from 18 months — paint is sealed inside a zip-lock bag, so there is nothing to spill or taste. Everything else suits ages 3 and up.
Which one teaches the most science?
Paper Towel Rainbow shows capillary action and takes about an hour to fully develop. The color travels up the paper towel on its own, which older kids find genuinely surprising.
Do we need special paint?
Standard washable tempera paint works for all six. Food coloring works for the ice cube version and makes the color change more dramatic.
How do you explain color mixing to a 3-year-old?
You do not need to. Just ask "what do you think will happen?" before each mix. The wondering is the lesson — the explanation can wait until they are ready to ask.
