The snails didn't seem to mind taking part in the activity, they didn't even retreat back into their shells when we changed their food colouring colour, lol. We also gave them a bath of clean water before putting them back where we found them.
I we did was for the younger boy's primary school. We were asked to bring in a repurposed pot with a winter plant in for the school garden. Not knowing much about plants I 'cheated' and made a pretend lollipop tree:
(Ignore the unkempt lawn grass on the bottom!)
The 'lollipops' are coloured table tennis balls stuck onto balloon sticks. I painted the ping pong balls with clear nail varnish to give them shine. The pot was found put out for rubbish by our local corner shop.
Finally, another shoe picture, fancy these?:
Available in my local River Island!
Thanks for looking and for any comments,
