So My friend and I were in a little prank war, and I figured a nice prank would be to somehow make him eat something spicy, as he is the whitest guy on the earth. But, as prank warriors may know, when you're in a prank war, you suspect EVERYTHING! He will smell tabasco or other peppers from a mile away and will never put it in his mouth. I needed something that will take him by surprise. So you can imagine the light bulb above my head when I figured out he changed his toothpaste from a white one to a green one :) WASABI TIME!

I talk Hebrew in this video, but its nothing important. Sorry about the video quality - its a phone's camera.

Step 1: Get Wasabi

you can buy it in the supermarket, and you can go to a sushi place and get some for free.
I chose the free way as you can see :)

It is also prefered if the toothpaste is greenish in color for obvious reasons.

Step 2: Make It Feel Like a Paste

Wasabi comes in many different forms and textures. Add water to and try to make it as close to the toothpaste as possible. Don't worry about diluting the wasabi - its potent enough...

**tip - you can extract some toothpaste out of the tube into the wasabi and mix them up. This way the texture and the color will match even better!

Step 3: Fill the Tube

Take a toothpick and start inserting wasabi into the tube. Slowly but surly the first layer that comes out of the tube will be wasabi filled goodness :)

Step 4: Don't Put a Hidden Camera....

Chances are the toothbrushing will commence in a bathroom. Don't be a jerk and put a camera there... the wasabi is bad enough.

On the other hand, if you're shot to the sink is clear, it can be a pleasure to watch :)
