To make this oobleck add 1 cup of water(with green food coloring) to 1 1/2 cups of cornstarch (corn flour in UK)
mix till it forms
oobleck should be a solid when pressed on but a liquid when relaxed
Then add in some Christmas decorations. You could add in some pine oil but you would have to make sure it is not eaten. Without the oil it is okay if a little one tries it.
My kids liked covering all the decorations and then finding them again.
Good for sensory play you can ask questions like
how does it smell
how does it feel
is it soft
what color is it
what color is the decorations
how many decorations are included
Just remember to have fun!!!
