This is an amazing little gadget! It's so cool! An excellent fun learning gift for kids! It's very intricate and tells you a lot about each organ. The heart beats and you can take a peek further inside at some red blood cells. It doesn't take ages to set up, you just need to download the app and follow the instructions from there. You can point the camera at someone wearing the t-shirt but the selfi camera works too if you want to point it at yourself!
