Fun science experiments to do with your kids!

Fizzy Magic Potion

Science Bob's Lava in a Cup

 No Hand Balloon Inflate

Each of these experiments were easily done with stuff I had around the house. The hardest part was the gathering of supplies and then the clean will see what I mean!

First experiment: Fizzy Magic Potion

you will need:
white vinegar
liquid dish soap
food coloring
baking soda
clear containers
excited kids

Fill each cup about half way with white vinegar. Then add in a couple squirts of soap and a couple drops of food coloring. Stir.

Get a heaping spoonful of baking soda...oh and a couple of towels...

I promise he was more excited than he looks in this photo.

Add the baking soda and get ready!

The fizzy magic starts right away...


It might get out of control. Not sure why the green wen to crazy!

But crazy it did go!

Remember how I said to have towels ready? You will need them here!

This was by far the favorite experiment of the day.

Second experiment: Lava in a Cup

you will need:
vegetable oil
food coloring
clear container

This experiment wasn't as exciting for my boys, but it was still fun to watch.

First you fill up the cup 3/4 the way with water. Then stir in a couple of drops of food coloring. Then slowly pour in some oil...I am not sure I used enough and perhaps that is why this experiment wasn't as exciting. Upon re-reading the instructions, I DID NOT add enough oil. You need to add 1/4 cup oil!

Once the oil is in, observe how it floats on top of the water.

Then sprinkle a teaspoon of salt over the top. The salt will immediately sink because salt is heavier than the oil. The salt with take the oil as it goes. Then as the salt dissolves the oil will float back to the top...hence the lava effect.

Our lava effect wasn't too, but not to profound.

I would try this one again with more oil next time.

Third experiment: No Hands Balloon Inflate

you will need:
glass bottle
4 TBS white vinegar
4 TBS baking soda

Add the vinegar to the bottle. Remind your kids it is NOT water or Sprite and that they DO NOT want to drink it...they might ask.

Using a funnel, pour the baking soda into the balloon.

Attach the balloon to the mouth of the bottle making sure that none of the baking soda gets in yet.
Let balloon hang to the side. Then have your little helper slowly lift the balloon over the bottle.

As the baking soda falls in there will be a fuzzy reaction and the gas released will inflate the balloon.
