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!

Magic Leprechaun Rocks

Lucky the Leprechaun is always up to some sort of mischief and this year he left some magical rocks!  Part of the fun was looking for the rocks and part of the fun was trying to break open the rocks with the “Magical Leprechaun Potion”!  Just 2 simple kitchen ingredients and some gold coins/rocks are all you need!

Here’s what you need to get started:

  • Baking Soda
  • Water
  • Measuring cup
  • Large Mixing Bowl
  • Tray for drying the rocks
  • Gold coins (I got mine from the dollar store)
  • Vinegar
  • Green food coloring (optional – but colors make everything more fun!!)

To make the magic rocks:

Combine 2 cups of baking soda and 1/2 cup of water (add some color to the water if you want colored rocks) in a large bowl.  Mix together well with your hands.  It will be crumbly.

Using your hands, make a rock shape with the mixture.  If it’s too dry, it won’t stay together, if it’s too watery, it will melt into a sloppy puddle.  Hide your coin inside the rock.IMG_1109

Let them dry overnight.  I placed mine on a baking sheet lined with parchment paper.  They will be delicate when wet.IMG_1111 The next morning, the rocks were hard.  Be careful, they break easily (You can also freeze them overnight to keep them from breaking as easily).  Note: this recipe will yield about 10 rocks.

To play: 

That naughty Leprechaun left the rocks in our backyard for the boys to find.

The boys were excited to hunt for the Leprechaun rocks! The boys grabbed one rock each and were very eager to break them open.

This was the first casualty.

The next rock was placed in a plastic bin.  I gave them both some droppers and some green Leprechaun Potion (Vinegar with some green food coloring) to pour over the rocks.

Bubbles and fizzing!!!  They LOVED it!!

Aha!  I see something shiny inside!

Such an easy and simple little experiment to set up with a St. Patrick’s Day twist.  The variations on this are endless: dinosaur eggs with dinosaurs hidden inside, Easter eggs with a little prize inside, etc…

Extension:

With the broken rock, we added the crumbly powder to a small “pot of gold” that I had out for my Fizzing Leprechaun Pots activity.

The boys used the leftover magic potion to create a bubbly green potion in the pot.
