Vortex cannon blows away houses better than the Big Bad Wolf

The Big Bad Wolf had to huff and puff to blow away the Three Little Pigs' houses, and even then he was foiled by the pig who used bricks. If he wanted to do the job properly he should have built a vortex cannon.

We looked at an air vortex cannon a while back, but by using some kind of explosive gas instead of air, this version built by the BBC appears to be way more powerful.

What looks like a smoke ring shooting out of the barrel is actually a ring shaped cloud formed by condensation in the rapidly moving gas, and it travels at something like 200 miles per hour.

The only thing I would question is the build quality of that brick "house".
