Footage of a man demonstrating that when you hook the bristles of two toothbrushes together you can lift some pretty hefty weights.

The video, filmed in Canada yesterday, shows the man holding a tooth brush which is tied to rope which, in turn, is tied to a dumbbell. He then intertwines the bristles of the tooth brush with another and lifts the weight with ease.

He first tries it with a ten pounds dumbbell and then performs the trick with a 25 pound weight.

He later wrote online: "I discovered amazing science when brushing two toothbrushes against each other.

"When you interlock the bristles on two toothbrushes, you can lift upwards of 25 pounds."

I discovered amazing science when brushing two toothbrushes against each other: when you interlock the bristles on two toothbrushes, you can lift upwards of 25 pounds. This is the video demonstration.
