This miraculous toy lived at my parent's home for years. My kids were always excited to see Grandma and Grandpa but really their Hoberman sphere was the big draw! It truly boggled my mind to see the different ways that they played with it as they grew older. first it was just a really cool odd-shaped ball, then it expanded so that they could stand inside of it, eventually it became a big butt when stood in and covered with a sheet, hahahahaha!!
I believe there is no more original and open-ended toy than this one. For you engineers and mathematicians out there the Hoberman Sphere cleverly combines mathematics and geometry to perform its delightful tricks.
Box size is 10.31 X 10.16" X 9.76"
