This great YouTube video is an instant Easter classic. Actually, it features an Easter classic — the Cadbury Crème Egg. Everyone loves those gooey, cream-filled chocolate eggs.

In New Zealand, Cadbury holds a yearly contest called Unleash the Goo! Entrants come up with an inventive way to smash a Crème Egg. Then they film it and upload it to YouTube.

This entry is the hands down winner. It’s an incredibly intricate Rube Goldberg contraption. It’s made entirely out of cardboard and plastic cups. It took six months to build. Three days of shooting and 200 takes were needed to get it right.
