eggs
Eggs for Easter. The one on the left is from an Ostrich (Struthio camelus), the one on the right a Rhea ( Rhea americana), the little one in front from a chicken (Gallus gallus domesticus), the one in the middle is from a Hadrosaur, possibly Saurulophus from the late Cretaceous 84 to 71 million years ago in Henan Province China, sadly it will not hatch, no matter how long I sit on it. And the colourful one on the right I'm sure you all know.

Something to try. Can worms hear?

Darwin was a great one for experiments, one of them was to do with worms and what senses they had.
He got a plant pot with soil and a couple of worms in in and rested heir hearing by putting it on a piano
and seeing if they reacted to different notes. What a simple and elegant experiment and an easy one to recreate,
you could try wood lice.
Something else to try. Enjoy the hols!!

This is great,
