Fizzing Leprechaun Pots

Baking soda and Vinegar are my two most favorite science experiment ingredients! They are inexpensive, always in the pantry and there are just SO many fizzy, colorful things to do with them.  Here’s my latest version, just in time for St. Patrick’s Day but would also be so much fun as a witches’ brew at Halloween

Here’s what you need to get started:

  • Baking Soda
  • Vinegar
  • Food coloring (I love my liquid watercolors)
  • Candy Kettles (any party store has them seasonally)
  • Bin/tray for the mess
  • Glitter (I used gold and green for St. Patty’s Day)
  • Teats, gold coins, etc… to hide in the pots (not necessary)
  • Droppers
  • Cups for the vinegar

To set up:

I placed a few pots in the bin.  I placed one treasure (plastic gold coins) at the bottom and added 1-2 teaspoons of baking soda on top. I sprinkled a little glitter on top of baking soda because glitter is sparkly and so much fun!IMG_1148

Pour vinegar (Leprechaun Potion or Witch’s Potion) into small cups.  I used 6 different colors to create a rainbow.

To play: 

I gave a small bin with a few pots inside to each of the tiny tots in my class.  I supplied them with a large dropper (more like a turkey baster-perfect for toddlers!)  And then the magic began!

That’s IT!  See, you can do this at home too!  And the little ones love it!  Adapt it for Halloween by placing plastic eyeballs, spooky fingers, creepy spiders, etc… for a spooky witches’ brew!  Or use plastic easter egg halves like I did with my Fizzing Easter Eggs experiment.  Or place some baking soda in a hollowed out mini pumpkin and make Pumpkin Volcanoes or into apples for Apple Volcanoes!  So many options!

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/st-patricks-day-fizzing-pots-science-experiment-color-mixing-activity/
