Science learning thus week - see through eggs

In science this week, we are doing an experiment.

Its about see through eggs. How awesome! 

 did you know all you need to have is 2 days, 2 plastic containers, an egg,vinegar, a fridge and patience  .. We have all those!!

1.put the egg in the container and cover it in vinegar 

2. Put the lid on and put it in the fridge

3. Wait for one day and get the egg out put it in the other container and do the same the next day you have see through eggs :) :0   

The reason it becomes see through is because the acid in the vinegar dissolves the egg shell enough that its see through.

There are bubbles at the moment . They are carbon dioxide. We have been learning about different gases with mum.

The egg shells are made of calcium carbonate and the vinegar breaks it down. The vinegar will permeate the shell. That means some of it sneaks into the shell. 

I cant wait to see the egg naked and the yoke slopping round inside the  membrane.

Here is a picture of me starting it off.
