Dice stacking is fun discipline for any budding magician, and they don't come any more budding than the kids in this video. One of them is a toddler.
The video, originally uploaded by two enterprising young lads working under the name That's Amazing, has racked up over 3 million views on Facebook in less than 24-hours. Not bad for a trick that takes about 30 minutes to learn.
If you want to get started with a little dice stacking yourself (you have no idea how many angry editors I'm fending off right now) the general consensus on The Magic Cafe is that Todd Strong's book and DVD on the subject are a good place to start.
On the other hand, if you were looking to get into the competitive field of being a crotchety jerk who feels threatened by the accomplishments of literal children, dive into the comments on that video. Like, damn.
