a little science experiment

The other day when I was cleaning out my kitchen drawers, I discovered many of my baking goods have expired... cocoa powder, soda bicarbonate, baking powder, and a brand new pack of chocolate chips. Sigh... that shows how often I bake :-(. I love baking but just too lazy could not find the time and energy.

So hubby saw me throwing out these items and he snatched the soda bicarbonate up. I was wondering what he's going to do with it. He excused himself and drove off with HQ; said he wanted to get something from the neighbourhood grocery store.

They came back with a small bottle of vinegar, and proceeded to the store room to rummage for more things, while talking excitedly. QQ was there too... just to enjoy the excitement.

They then went to the car porch; QQ following them like a puppy. Hubby set my old saucepan on the floor, looped off the top of an empty plastic bottle, and set this up with the help of ciplak playdough, which was already drying up. The kids were never allowed to play with these, as I'm not sure about its toxicity. They have their own set of safe Playdough to play with.
By now, everyone would have guessed what they are up to, right? ;-) I was hoping that the expired bicarbonate would still work.

Hubby threw rocks of bicarbonate soda into the opening of the bottle... And poured in some vinegar.
Bubbles started foaming very quickly...
a "volcano" has errupted! "Lava" flowing down the sides... would be cool if we added some red colouring. Simple experiment. But the kids were entertained enough :-).
