Late to the party as ever! Is it the work of the devil? An interesting toy? Does it stain? Stay slimy? Best recipes? Glitter? What do you keep it in?
DS has a birthday coming up, is it something that would be feasible to make? There will be 6 kids, 6-9 years old, in a small flat so need to keep them occupied. SN means no games are possible.
What other fun science activities are there? Preferably something they can make and take home so I don’t have to worry about party bags.
