Daddy and I have been doing lots of science experiements recently. Today we tried out our glass cutter.

We washed some bottles and then used the machine to score a line around each bottles circumference (the distance all the way around the bottle).

Next we slowly poured very cold water onto the score mark, whilst turning the bottle, then we poured boiling water over it, still whilst rotating the bottle. After a few go’s of hot and cold the bottle just falls apart at the score line.
