This science project for kids has been all over the internet and for good reason, it’s so cool!
I planned this for our final science project of the year at preschool and vastly overestimated the amount of milk needed. I bought about 4 gallons and ended up using less than one. So it goes!
The basic concept of this project is that when you add a little bit of dish soap to milk, then drop in some food coloring, the colors stay separate, at least for a little while, and swirl around to form what I would deem very artistic and abstract paintings! But beware, too much swishing and swirling and you’ll end up with brown muck fast. Of course kids don’t seem to care!
- Milk (Almond milk works just as well)
- Food coloring
- Shallow plate or wide bowls
- Fill a plate or bowl with milk.
- Drop in at least 2 drops of each of four colors of food coloring. The more variety of colors the cooler the painting.
- Generously dip the end of a q-tip in dish soap.
- Now dip the q-tip into the milk next to a drop of color.
- The first thing that will happen is the color will burst as soon as the dish soap hits it. It’s a great effect but very short lived. Once there is a little dishsoap in the milk it no longer “bursts”.
- Gently swirl the q-tip through the different colors and you’ll see little rivers of color start to form.
- Continue until the colors begin to mix and become brown. Empty your plate/bowl and repeat.
- For a variation we premixed the milk and dish soap. You won’t have the color burst effect but it does seem to keep the colors separate a little longer.
