Add to your bundle and get these learning toys for free! New and unopened bundle of three packages from Mad Science. Not sure what is inside but I assume it is a science activity with instructions and supplies. Science blind bags!! The largest package has a graphic on the front of an Eagle and a pyramid. I'm guessing this is the balance bird activity where you can balance the entire bird on its beak and it doesn't fall off the tip of the pyramid, even though it looks like the bulk of the weight is off to one side. Kids learn about the center of gravity. One of the packages has 3 disks and what looks like a flash light depicted. This one could be the projector toy where you take a flash light you already have and put the disk in front of it, making a shadow on the wall of paw prints or what have you. Kids learn about animal tracks. The smallest package has 2 cups, eye mask, and some kind of contraption. This looks like the lame package but if it's the activity demonstrating the magnus effect, it could be the coolest one (spin 2 cups to show how air pressure causes lift). It could also be demonstrating peripheral vision. Hmmm not sure. Let's just call this bag the mystery bag!!
