Simple Science experiment for grade 6

Sorry to sound opinionated - but why isn't your DS doing this himself? Why are you bailing him out?

The mentos and fizzy drink can take an eye out so be careful! Also cornflour and water mixed together to make gloop is good - kids make a big batch of it and then they can softly put their hands in it and if they punch it hard, it is firm on top.

There is one with milk and food colouring but I can't for the life of me remember what now. Off to think, loved teaching grade 5/6 for years especially on science day!
