Icy-poles for Room 20

Hi everyone, we found a cool book in our classroom about kids cooking and on one of the pages we saw how to make icy-poles. We think these will be a very cool idea for the summer and we are asking all parents to please have a look in your cupboards and if you have any spare ice-block trays that you would be happy to donate to room 20 then we would really appreciate it. Thank you so much from, Brooke and Lilly
