[Leica] A snapshot of my 2-year-old grandson

[Brian Reid]

My grandson Carter, who will be 2 years old in a few weeks, was 
experimenting to see which objects will sink or float in a bucket of 
water. He was delighted to discover that green chalk sinks quickly 
whereas blue chalk remained floating.

The smudge on his face is blue chalk from an earlier experiment.
