Greg and Mike, or Mike and Greg, take roasting chestnuts to a whole new level in this, the seventh explosion in the '12 Explosions of Christmas'.

Using flame cannons with a solenoid valve (that's an electric fired valve to you and me) they roast seven bags of chestnuts so badly they look more like black coal when they're done.

Why did the guys use a solenoid valve? So they can set light to the propane remotely -- using 80,000 volts -- you don't wanna be anywhere near that baby when it goes off!

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