More kitchen science

The day started off pretty gloomy and rainy so we got out some of our library books to look for some experiments that interested us.

We came across this one on reactions involving acids and alkalis.

First up we found an oxidised copper coin and put it in lemon juice to watch the acid react with the oxide and remove it.


We then found another acid/alkali experiment which used red cabbage (aha! yes we actually had one of those in the fridge!).

First Nathan chopped it up and we boiled it till the water turned purple. He then wanted to pop the thermometer into it and watched the temperature drop as it cooled.

We then lined up 3 glasses and poured a some of the purple liquid into each.

Into one glass he squeezed a lemon to see the acid reaction (the pink one).
Into one glass he dropped a lump of soap to see the alkali reaction (the green one).


And then my funny girl drank from the control glass and the acid reaction glass with a teaspoon lol.

Very cool!

We then raced out to meet the kids nannie and I bought them a decent winter duvet each since their old ones are falling to bits.

Home for lunch and a friend came over with her two little boys for the afternoon.

Lots of reading after dinner while waiting for dad to get home.
