Rewiev of Newton's Cradle Balance Balls from Tinydeal.Com

These small ordinally looking balls on a string are perhaps one of the silliest things i ever got. They do actually work, and only cost 3.26€. you can buy it from here http://www.tinydeal.com/newtons-cradle-px1oojq-p-92983.html

Great for office on those boring long drawn days, or as a gift.
