Based on the web site I’m assuming this is a couple of 13 year olds
demonstrating an age appropriate understanding...but I’ve been wrong about
this before; X-33 comes to mind....

Not much mention on how they deal with aero drag.
"We should be able to extract some of the potential energy of the

falling up, again using Newton's law of equal and opposite action"
So, dealing with aero drag by coming up with a rationale for treating
it as thrust instead. Neat trick!
Yes, I rather liked that one.
In another neat trick they treat propellant as ballast, so just throwing
it away makes you go faster - and using it as rocket fuel makes you go
fasterer twice over!!
It's only a wonder the ISp isn't even higher!
Shame they failed their science high school classes ...

Also, their "pending patent" for burning lift gas as fuel doesn't exactly
seem to be anything new ...
