Klever Kits 3-in-1 Dinosaur Fossil Dig Kit STEM Learning Toys with Glow in The Dark Dinosaurs Toy and Sensory Play Sand, Gift for Kids Aged 6+

Our boys (2 %26 4 years) are obsessed with digging for dinosaurs. This kit was cool because the blue one is soap and comes with a little bag so they can use it to wash their hands. It was also fun that the volcano has plaster plus kinetic sand. The 4yo got a kick out of putting “skin” on the dinosaur bones. Lots to keep their interest. It is a fairly messy activity (and took them several days at an hour or two per time) so I recommend doing it outdoors or somewhere you can contain the dust and soap scraps.
