The Assassin's Water Bottle

This water bottle allows you to carry two different liquids and dispense them from the same nozzle separately or together at your command. It's a collaboration between myself and Steve Mold that you can pre-order now.

It all started when Steve and I were talking about the physics behind the Assassin's teapot, and I said something like, "Wouldn't it be amazing if there was a water bottle that worked in the same way?" Then he probably said something like, "You have such good ideas, Michael, and you're so handsome." I think that's exactly how the project began.

Over the next few months, we designed a portable version of the Assassin's teapot: a double barrel water bottle with no moving parts that uses just surface tension and air pressure. We even designed mathematical koozies that can hide the secret or be removed to reveal and teach.

We call it the Assassin's water bottle. We are only going to make a limited number of these, so pre-order today. The future of drinking starts now. The future of poisoning people stops now. Do not use this for that.
