Two mother-in-laws from Wisconsin hilariously misfired their smoke flares at a gender reveal party and ended up covered in blue powder.  

The couple was hosting a Halloween themed party at their home to announce they were having a boy. Their moms were given small smoke cannons to set off at the crucial moment.

The women activated their flares, not realizing they were holding them upside down.

Instead of projecting the blue smoke into the air as intended, they fired the flare into their stomachs, staining their tops in the process.
