RAINBOW Science experiments for Kids



As some of you may know, we love exploring with Science in the bath.  All the mess is contained, there is a water source nearby, and clean up is a breeze.  For our Lucky Leprechaun Lab I embellished Rosie's bath with simple St. Patrick's Day accents.  I colored the water green using food coloring and stuck shamrock foam shapes purchased from the Dollar Tree all over the walls. 


I had all the needed items for our experiments set out or close by on the floor.

Experiment #1
Make RAINBOW Rain

Making rainbow rain is a simple twist on the rain cloud experiment we recently shared as part of our Weather Experiments Lab.  Rosie loved the activity so much I knew she would love to do it again.  Making one simple altercation turned this into a whole new activity to her too!


To make RAINBOW Rain you will need:

  • A clear container
  • shaving cream
  • food coloring
  • water

Fill the container 3/4 with water.  Then cover the top with shaving cream to create cloud peaks.  Have your child drop food coloring on top of the cloud in rainbow order.  Then have them syringe water over top of the food coloring drops to make it RAIN!





RAINBOW Rain!



Not only was the rainbow rain beautiful but the RAINBOW clouds were too!



Rosie loved this experiment even more with the magical RAINBOW rain!



The Science- as you play talk about how rain is made and how rain clouds form.




Experiment #2
Magic Appearing Rainbows


For this experiment I hid rainbows under a bed of baking soda for Rosie to magically discover.  I prepared the tray of baking soda prior to bringing her into the bath so she had no idea there was color hidden under the baking soda.  To do this I covered the bottom of a tray with drops of food coloring in rainbow order.


Then I carefully covered the surface with baking soda.  I gave Rosie a pipette and a cup of vinegar for her to unveil the hidden rainbows.





She absolutely loved this!  She was so surprised when the color began emerging and loved hunting for the magic rainbows with the pipette of vinegar!


 Such beautiful and fun Science!




The Science- discuss acids and bases and why they react.




Experiment #3
Magic RAINBOW Milk


We had done this experiment twice prior to this and Rosie has loved it all three times!  Each time I presented the experiment a little differently, making it like a whole new activity!  This is actually a great illustration that children don't always need a new activity so much as activities presented in slightly new ways. 


To make Magic Rainbow Milk you will need:

  • a shallow dish (we used a pie pan)
  • Half and Half or whole milk
  • Food coloring
  • Dish soap
  • A popsicle stick or similar 

Cover the bottom of the container with half and half.  Then add drops of food coloring to the outer pie surface in rainbow order.  Since Rosie added our food coloring it was a bit out of sorts which doesn't matter too much as long as the colors don't touch.






Add a drop of dish soap to the popsicle stick and dip it in the middle of the pie


At first the colors will jump to the outer surface, but soon rainbows will appear and magically swirl and spin 







So simple and so much fun for kids!


The Science behind the fun can be found here.



Rosie had so much fun with our magic RAINBOW Science!  These activities are great for St. Patrick's Day or anytime!  Rosie loves rainbows so I know we will be doing these again real soon!
