The ALS Ice Bucket Challenge has taken the internet by storm as tv stars, musicians, athletes, kids, students and everyone in between have thrown freezing water all over themselves in an effort to raise awareness (and millions of dollars) to help cure the neurodegenerative disease. So when [Christopher] was challenged by a friend, he decided to make an icebucket backpack that would pour the liquid from above without having to use his hands.
The wearable device uses a Barometric pressure sensor that is triggered when air is blown into a tube. This sensor is attached to an Arduino Uno. Once activated, the pouring process begins drenching the person below in ice cold water. It’s a little unnecessary, but it gets the job done in a fun, maker-style way. Now if you make something similar, don’t forget to actually support the cause and donate money.
