Joseph (4.5) asked to make an elastic band guitar, after seeing the idea on cbeebies. They used a tissue box but as we didn't have one we raided the recycling box.
I wrote a G on the cheese triangle box to reinforce G for guitar. Joseph was able to stretch most of the elastic bands on himself, only asking for help on a couple of the tighter ones.
Daniel didn't want to join in so Joseph made 2 so that they could each play with them. The cardboard one soon collapsed, however the black plastic tub is still going strong a few days later.
