Ok, so after my dramatic disclaimer yesterday I feel the need to say that doing experiments with dry ice is fun. Just not while breathing it! It gave both my big kids a stomach ache that night that they were playing with it.
Yesterday we tried a safer dry ice experiment… Singing spoons!
This is one I will have to get video of for the full effect, but basically it makes the spoon ‘sing’ with the below zero temperature. We were very careful and used chop sticks to pick up the dry ice and put it on the spoon… then of course, after we were done, we dropped it into hot water in a bowl:
That is always a crowd pleaser, as long as no one is sticking their face in it.
