Right then, push... this clamp right here an- woAH.

Toby had to quickly scramble to grab hold of the radiosonde because it was already making a bid for freedom. It was yet another case of him having trailed off when he was supposed to be concentrating on instructions, but it was fine. Everything was fine. He still had hold of it.

When Professor Flamsteed was done talking, Toby didn't waste any time before making his way over to the classroom window so he could get started. He flung open the window and let go of the balloon so it was off outside, and then hurriedly pulled it back closed again. But it was enough for him to REALLY appreciate how cold it was out there. Plus, being overly sweaty from all that running in thick layers was going to be a problem. Just that one gust of cold cold wind had been enough to start Toby shivering like mad, and soon enough everyone else would be throwing windows open, and it would get even colder.

It was best to move away from the windows, which Toby very quickly did whilst keeping a careful eye on his receiver, practically willing for the number on the precipitation temperature thing to go above zero degrees. Every now and then the Hufflepuff gave a shiver, because it really was very cold (and he was considering chucking another sweater back on) but kept his eyes trained on the receiver. The highest it would reach on his was about -10 degrees, but there was still time, right? He'd just keep watching.
