Fizzy ice cube (Dinosaur excavation)

The day before mix baking soda with some water and put on ice cube tray, put some dinosaurs in it and on the freezer until you are ready to use it.

on a container/ sensory bin, put some baking soda ( it will be the snow) put the ice cube on top if it. Give some white vinegar to your child. kids love to watch how the vinegar reacts with the baking soda.
