26 degrees in here. so it is a lot warmer in here, it s actually lovely in here. and the idea is to test materials, test them and see how they perform in these different conditions, as i ve been discovering. this chamber goes down to 20, and as well as creating a lovely snowy day like this. whoa! ..it can also do this. create a pretty fierce gale. and it could do a rainstorm too, although today, we re doing it outside. so thank goodness they do tropical too. it s the costa del salford! from the outside, you would never know what s going on, would you? back in the cold. so let s take a look at what goes on inside these houses.
