Hi all, Just wanted to pick your brains. I am doing a project on lighthouses and asked the children to bring in toilet rolls, kitchen rolls etc to make the shape of the lighthouse. The children brought loads of them in after the hols and I was really pleased, then a TA in school told me you weren't allowed to use emply loo rolls in the classroom because of spreading disesases. I have never heard this before! She said we could use them if they were microwaved for 3 minutes. Will they be ok to use if I do this? Can you microwave loo rolls? Thank you!
