Inspired by viral challenges that have gathered billions of views across the Internet, this game tests one's ability to stay calm under pressure. Players wear the Cool-O-Meter that measures their heart rate, and the opposing team rolls the dice that will determine how they'll try to get the player to get flustered. A change in heart rate effects the meter and when the meter gets high enough, the lights get to red, the alarm will sound, and the opponent wins for making that player lose their composure. To play the Don't Lose Your Cool game, one player puts on the Cool-O-Meter unit that will measure their heart rate. Then, their opponent rolls the 3 action dice. What shows up on the dice corresponds to actions the opponent can do to get the other player to get all flustered and react within 30 seconds. For example, opponents might have to get up close to the other player and sniff them, stare them down, or make pig noises -- all in an attempt to increase the player's heartrate. Who will stay calm and collected and who will break under pressure? Includes Cool-O-Meter unit with built in timer, lights, and sounds, 3 action dice, and instructions.
