These are from the Stressmas eve party.
There is some type of cylinder that explodes confetti and candy up in the air ( and on top of your head if you're not paying close attention )that the host used at this party.
The hazards of this are twofold, the initial concussion of the candy cannon with the resulting fallout and
then the rush of kids to get to the candy that landed on or near you. They'll bowl you over if you're not paying attention ( or are trying to take photos and not watching ).
You want to make sure that you are clear of where that candy lands.
It was a big hit with the kids and was fun to see them having such a good time with something so simple.
