I had to do two science experiments today. One of them required plastic bottles, so I just bought some Poptops and put the cordial in a jug.

For the next experiment I had to fill a jug up with water and add food dye. And then I went and did a very Tarwa thing and chose red food dye, which happened to be the same colour as the cordial! So there I was with two jugs of red liquid that looked exactly the same.

I just stared at the two jugs and tried to decide which one was the cordial and which was the the dyed water. It wasn't easy.
