Re: Digging for worms
at school we did an experiment to count the number of worms that came to the surface
On 1m square we put soapy water, on another we 'tapped' the ground on another we watered it from high like rain and another we used as a control.
The soapy one won, alearly the way they wriggled showed they were irritated by teh soap.
'Rain' came next then 'us simulating rain'
control was next to zero.
so without the ability to put soapy water down or make it rain they are doing teh best they can!!!
