Walking Water

This week we kept it simple!

All you need for walking water is:

• 3 Clear cups
• Water
• Food colouring
• Paper towels

Fill TWO of the cups with water.

We added food colouring to both cups.  You can add any colours but the kids wanted to add blue and yellow.

We added paper towels that looped between the cups.  The middle cup (the cup without the water) had both paper towels in there.

.... And then we waited and watched the water climb up the paper towels...

... And into the middle cup...

... And then the magic happened! The colours mixed together in the middle cup

and the water turned green!

 

Very cool :)

 

E even asked me "what would happen if we had blue and purple and red and yellow and brown food colouring and we mixed them all together?" ... Love his thinking mind!

NOTE: This is the second time we had done the experiment - the first time I used quite deep plastic cups and it didn't work as well - it worked a lot quicker with smaller, shallow cups.  If it is not working as quickly as you like you can change cups or try putting the cups with the water at a higher level than the empty cup - gravity will help speed up the process.
