it does not go too high? now, we brought along a friend to film the test. remember gav? he is one half of the slo—mo guys who helped me get egg all over my face a couple of weeks ago, and he is going to be capturing the action at 2,000 frames per second. that's 80 times slower than real life. the only thing is, he, like the rest of us, has to be hundreds of metres away when the rocket ignites. so i'm going to leave him to set the remote triggers and work out how his camera's not going to be incinerated, and we will come back later in the programme to see a rocket ignite like you've never seen before. scotland — there's no better place to enjoy nature.
