we made an erupting volcano! bicarbonate of soda, vinegar, washing-up liquid and red food colouring.
The volcano is a small plastic mould that I found in a charity shop but there are so many tutorials out there on making ones of plaster (I bought some plaster moulding rolls from Hobby Craft for £1 each with the intention of making one)
This worked really well - given it's a small thing. Also, R extended the activity on his own - he got some plastic dinosaurs and they "all died beside the volcano and became fossils"
a bit of fun on a Sunday afternoon that took-up around half an hour. one for the childminding list of to do's!
