Fizzing Easter Eggs

The tiny tots in my class LOVE baking soda and vinegar experiments and I’ve posted several different variations of them.  Here’s my latest version, just in time for Easter.  So grab an extra pack of eggs at the dollar store and set up this fun experiment in a few minutes!

Here’s what you need to get started:

  • Baking Soda (Bunny Powder!)
  • Vinegar (Bunny Juice!)
  • Food coloring (I love my liquid watercolors)
  • Plastic Easter eggs (I have amassed a large collection over the years)
  • Muffin Pan or styrofoam egg carton (cardboard will leak and make a mess)
  • Glitter (because sparkles are FUN)
  • Droppers (I use the ones I get from the pharmacy with my kids’ medications)
  • Cups for the vinegarIMG_1244

To set up:

I placed a dozen halves of plastic easter eggs in my muffin tin.  (You can also use a styrofoam egg container but don’t use the cardboard ones.  Once the vinegar gets added, you will have a leaky mess)I placed about 1/2 tsp of baking soda into each egg and sprinkled some glitter on top.  You could also add some foam bunnies or beads or anything else for some extra fun!

Pour vinegar (Bunny Juice) into small cups.  I used 6 different colors to create a rainbow.  Kids love choosing different colors.

To play: 

I placed a muffin tin with the eggs in front of each of the tiny tots in my class.  The colored vinegar was ready for them to play with droppers.  The tots already know what to do with the droppers at this point 🙂

They added their favorite colors to the eggs and watched them bubble and fizz!  So easy!  So fun!  So colorful!

That’s IT!  See, you can do this at home too!  And the little ones love it!  Adapt it for any seasonal occasion as I did with my Fizzing Leprechaun Pots for St. Patrick’s Day, Fizzing Christmas Trees or as Pumpkin Volcanoes for Halloween.

 Science Behind the Activity:

This is a twist on the classic baking soda and vinegar experiment.  Baking soda is a base and vinegar is an acid.  When combined, they release carbon dioxide gas (the bubbles).  The fizzing and bubbles are just way too much fun for the kiddos!

Here’s where I got my fizzy idea from: http://littlebinsforlittlehands.com/fizzy-eggs-easter-baking-soda-science-experiment/
