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

Back out in the field, Greg and Mike upgrade their explosives from low to really high. Previously in the science behind the 12 Explosions of Christmas, we've seen 8 Brussels sprouts fired out of a cannon using black powder and 12 mince pies popped with flash powder. Both of these powders are a composition of different chemicals that burn slowly.

But for their three man-sized Christmas crackers, Mike has something else in mind. He's using a high explosive to detonate each cracker. This means breaking the bonds of the chemical at a molecular level, and the chemical reaction follows after.

There's no getting up close to this one. The boys stand back at the other end of the field to detonate the crackers remotely. Check out the awesome slow mo! It's one almighty crack.

There are just two more videos to go until Christmas, so make sure you hit SUBSCRIBE so they appear in your YouTube home feed when you log in.
