I'm getting my kitchen window ready for St.Paddy's day and came across these decor pics from a couple of years ago...
Which led me to the post about this super easy little rainbow experiment...
(put a little bit of milk on a plate, add several drops of food coloring followed by a few drops of Dawn dish soap. Swish the plate around a bit and watch the colors move!)
Which got me thinking about another fun rainbow idea I saw a while ago.
We set up seven water glasses, 4 with food coloring and 3 without
(red, none, yellow, none, blue, none, red)
We put paper folded up paper towels into the glasses (and actually added more in between the others after I took this pic) and then watched the colored water start "walking" up the towels.
It took WAAAAAAY longer than I anticipated (and I had to help it along a little bit while the kids were taking baths), but we ended up with awesome mixed colors.
Note: After doing a little bit of reading... I think that this would have worked better with cheaper paper towels. hahaha I use Bounty and they didn't pass the water between the glasses as well as others because they actually hold onto the liquid.
We also set up a ring (red, none, blue, none, yellow, none and then that connected back to red) and used skinnier strips of paper towels and it seemed to work better.
This was super easy, completely free (I had the food coloring on hand) and brought up several great topics of discussion...
- Primary and secondary colors
- Shades of color
- Patience ;)
And Mason's favorite part? Dumping all of the cups of colored water into the pitcher to make black water :)
This would be easy to scale down if you're not wanting to do a full rainbow. You could even set up three cups with two primary colors on the outside and plain water in the middle and watch them mix.
