Fizzy Warts

Last weekend was SO MUCH FUN!!  A good friend’s son turned 10 and requested a ‘Scientist Birthday Party’.  The kids did several experiments, including Elephant Toothpaste, Blowing up a Balloon with baking soda and vinegar, Electromagnet, and a few others.  My contribution to the fun was Fizzy Warts, aka ‘Fizzing Whizbees’.

I developed this fun experiment in College as a demo to do for kids in Chemistry Club Magic Shows. 

The recipe is simple, the ingredients are easy to find and the result is– COMPLETELY GROSS!!  Your kids are going to LOVE this!

PS- the warts taste like sour patch kids!

Fizzy Warts

  • 3 tsp citric acid (natural food store or by the canning stuff)
  • 3 tsp meringue powder (crafts store by cake decorating supplies)
  • 2 tsp baking soda
  • 4 single serve envelopes green koolaid (sugar free)

Combine all ingredients in a jar.  Make sure your baking soda is lump free! 

To make a wart:

1.  Place a few drops of water on the back of your hand.

2.  Sprinkle a pinch of the powder on top and watch the wart fizz and grow.

3.  Once the wart is nice and high, lick it off!  The foam is sweet and sour like a sour patch kid.

You can experiment with different flavors of koolaid– red could be a fizzy boil! 

We also tried putting 1 tbsp powder in a pint-sized jar and adding about 1/4 cup water.  The foam filled the jar and the kids had fun eating it with a spoon.


The water provides a medium for the baking soda, a base, and the citric acid, an acid, to react.  The reaction produces carbon dioxide bubbles that are trapped by the powdered egg whites in the merigue powder, making a foam.  Isn’t science fun?


Something’s Brewing! Homemade Vanilla Extract

I had vanilla beans.  Lots of vanilla beans.  And no time to make pastry cream.  Oh well.  Might as well put them to good use!

Fresh vanilla beans are expensive– but the flavor is absolutely magical.  Those tiny little black seeds explode with aromatic comfort. 

Do you know how easy it is to make your own vanilla extract?  And did you know that the homemade version will taste about 100 times better than the little bottle with the red lid?  Oh yes, it will. 

Vanilla Extract
1/5th bottle of Vodka or Rum (get one that is mid-range)
2-3 vanilla beans
1.  Pour off about a half cup of the liquor (or drink it).
2.  Split the vanilla beans lengthwise, then scrape all the seeds out with the blade at the tip of your knife.
3.  Put vanilla seeds and pods in the liquor.
4.  Let sit in a cool dark place for 3 to 4 months.
Should be heavenly just in time for fall goodies!

After just one week, the liquor is starting to darken.  You know its ready when it is a deep dark brown color and smells like vanilla when you open the bottle and take a tiny whiff.
