Silly Science - What will happen when you add mentos to Coke?

2-liter of Coke
Mentos

Open the pop and place on the lawn. Quickly put in the mentos and run. It's messy and fun! My photos didn't work well enough to post onto this so go and watch these people with way to much diet coke, mentos and time on their hands!

Silly Science - Can an egg bounce?

This started as an experiment to see again what happens to an egg shell in vinegar (since both girls didn't see the results last time) and see if you can bounce a raw egg - it didn't all turn out as planned.


One egg was put into a glass and covered with vinegar. The other egg was colored on with a crayon, then put into a glass and covered with vinegar. We were supposed to see if there was a difference in how the shells disappeared with the crayon or not.

They checked their eggs the next day, before we could bounce them the girls tried to poke the shell-less eggs. We never got to bounce them. It is a cool way to teach osmosis though.

Silly Science - Dirty Pennies

The girls put salt on dirty pennies then dropped vinegar on top of the pennies. (It makes hydrochloric acid - just what every parent wants their kids playing with!) They had fun cleaning up the pennies and making them shiny again.

Baking Soda & Eggs

We are playing with baking soda again. The girls had fun seeing what baking soda would do with vinegar (mom, it's a volcano we've done this before), water, orange juice, and grapefruit juice and Coke.

I'm going to have to start buying my baking soda at Costco!

How it works: Bicarbonate Soda reacts with the acid, releasing carbon dioxide which bubbles up through the liquid. The more acidic the more bubbles there are.

She also put eggs into a glass of Coke and a glass of vinegar to see what they would do to their shells.
