Instant Zombie-Proof Shelter

So, this was sent to me this week and I have to say, it is one of the coolest things I've seen in a long time. Pictured above is a pop-up, concrete, fire-proof, weather-proof, sterile, bunker. This is a thing of the future because it requires 3 easy steps.
1) Unfold
2) Pop-up
3) JUST ADD WATER!

The canvas material used to make this shelter is infused with concrete so when you spray it down with water, just wait 24hrs for drying and hardening and you've got yourself one awesomely everything-proof shelter. Check out the video below for more details on how it actually works.
