In the video, a man can be seen putting flies into a freezer for about 5 mins, causing them to be “unconcious”. Following, he successfully tied a string around the fly’s head carefully, after trying for more than an hour.
The video description reads: “In this video I catch a fly and tie a string to it in order to measure how much weight it can lift! First I slow down their metabolism by cooling them down then I tie a string around it and attach duct tape weights to it in order to see how much it can lift! I was surprised how much it could lift!”
