8 Brussels Sprouts Cannon balls | 12 Explosions of Christmas with Greg Foot | Head Squeeze

To see Greg and Mike's full '12 Explosions of Christmas' bonanza here:

Day 8 in the '12 Explosions of Christmas' sees Greg and Mike firing Brussels Sprouts out of bronze cannons. That's one way to serve up Christmas dinner!

To set them off they placed just 10 grams of black powder, which is refined gun powder, into the cannons, then inserted some wadding and one single sprout per cannon.

The effect was destruction of Greg's bubbly tower! And a hole right through the table!

If you know how the guys could have worked out the speed of their sprouts let us know in the comments.
