Twist in Time

You’ve mixed colors, but have you ever unmixed and separated them? This experiment from Steve Spangler Science is a demonstration that almost has to be seen in person to believe. Otherwise, you’re likely to say, “It’s fake… there’s no way that could happen!”

You are going to need

• 4 clips
• 3 different food dyes
• Glass
• Smaller glass
• 3 pipettes
• 3 small tubs
• Jug of water
• Liquid hand soap

Directions:

1. You really need adult supervision for this.
2. Take the glass and fill it with a small amount of liquid hand soap.
3. Put the smaller glass in the larger glass.
4. Fill the smaller glass with a lot of water to weigh it down.
5. Take a clip and put it on the rim of the larger glass.
6. Take another clip and place it on the opposite side.
7. Take a third clip and place it in the middle between the 2 other clips on the rim of the larger glass and leave a place for the last clip.
8. Take the 3 tubs and put the hand soap in each of them. Add a few drops of 1 of each food dyes to each one. Make sure they each have different colors. Use the pipettes to mix them together, using different ones to not mix them up.
9. Take the pipette and suck up the liquid soap with the dye and put it in-between the 2 glasses from before.
10. Put them in the spot for the 4th clip and do it with each 2 times.
11. Put the last clip after this.
12. Slowly rotate the smaller glass in one direction. You will see the colors begin to mix inside of the soap.
13. Now, rotate the smaller glass in the opposite direction. The colors will begin to separate and “unmix!” No, it’s not a camera trick!
