Science Class

Today was Ms Aliaa 's second last day .
She's going to leave tomorrow which means this is her last week in school .
Today teacher call us to do the Chapter 5 : Air Around Us 's experiment .

We mixed Sodium Hydroxide+Lime Water+H2O+Bicarbonate Indicator and guess what ?

It turn into blue .
Its like the gel pen blue colour .
I love the colour .
The upper layer is lighter by the colour and the lower part is darker .
It is because of lime water . It made it cloudy .
We also test it .
Its alkaline .
Cool rite ?
Actually we wanna use the liquid to refill our pen .
Bt no one 's pen need to be refilled .
So ...
We just throw it away .
Next time i wanna try again by adding sulpur powder .
I bet it will be an loud explosion in the lab ... haha xp

p/s : Ms Aliaa is goin to leave ...
