Home grown scientist

I am 5 years old and in Mrs Cribbin's. At home I like to do experiments. 

Here is my timer. I made it with 2 water bottles, a short straw, sticky tape and some water. 

My Mummy helped me make a hole in the lids. The water spills slowly down into another container through a straw.

You see. That's a lovely timer. It's a fizzy timer. You just shake it to make it go faster. I must roll up my sleeves so I don't make a big mess. I do singing glass and snake bubbles experiments too.
