Knife Walk

Knife Walk

You will need knife and a bobby pin.

Step 1: Turn your knife so the blade is facing up.

Step 2: Then take your bobby pin and stretch it 1cm apart.

Step 3: Now take your knife and turn it so the flat side is facing up then squeeze it tight.

Step 4: Then take your bobby pin and place it on your knife and observe.

As you can see the bobby pin walks along the knife. The reason is when you are holding it tight it detects the littlest movements and your muscles never stop moving even when you are sleeping.
