We’ve covered the water rockets of George Katz and Air Command Water Rockets before. Now comes this impressive video of another of his two-stage rockets with cluster motors achieving altitudes of over 800′! As usual, great slo-mo and on-board video footage. Since it’s Plastics month, and people are asking what fun, cool, useful things they can do with plastic water bottles, here’s something very cool!

There is tons more information available on Air Command about building such rockets, what parts you need, flying tips, etc.
