The guitar one made me physically cringe because it felt the most damaging. The camera and eyeglasses can be cleaned; the orange juice could be thrown out and replaced. I suppose you could restring the guitar but it just feels like there’s a potential for further damage somewhere on the bridge or the other parts I forget the names of.
We have 8 and 10 and we have just been thinking that maybe the 10 year old could handle it. Sadly the 8 year old is really sensitive so no time soon.
