This disappearing colors experiment is quick, simple, and easy to do. But don’t let its simplicity fool you – it makes for a really cool trick! Although your kids may think it’s magic, it’s actually just a really neat science activity. It’s also a great demonstration for why bleach will turn your clothes white.

 All you need to do this disappearing colors experiment are:

I started by filling two tall glasses with water. I then used liquid watercolors to color the water in one glass red. (I believe food coloring would also work in lieu of liquid watercolors, but I did not try it myself.)

I then filled my plastic pipette with bleach.

And I put the bleach into the glass with red water.

The effect was not instantaneous, but the water did begin to lose color fairly quickly. The longer we waited the more the color disappeared.

    This looks like great fun for my children! We don’t have a plastic pipette, but a straw works well for us instead. Thanks for sharing. 🙂

    My church used a similar activity once to show how Jesus takes away our sins (as represented by the bleach taking away the red stain) and the kids were all amazed at what happened.
