These Siftables are little computers that are about palm size. They have motion sensing, able tell how close they are from each other, they are wireless devices that communicate, and they have a graphical display on a little screen. These siftables are able to many different neat things.
You are able to add numbers together with the little Siftable blocks.
You are able to have a color on the blocks and poor it into another by tilting it and it changes the color of it by how ever long you tilt the block.
You can do many more things by pluging them into your computer and progaming whatever you want on to the Siftables. I think that this will be a product that many people will buy for not just children but for other ages to because the Siftables have such neat features to them.
