We were hiking in the mountains for a school field trip, and an ENORMOUS cloud was moving 60 MPH and then within 1 minute of seeing it, it was raining huge drops really hard, and hail the size of bolts.

We found a shed and had to fit 75 kids in it for 20 mins, after nothing changed, we sent groups of kids running down the mountain to the buildings. It was SO MUCH FUN.
Everyone smelt like wet dog, there was a rockslide on the road which took another 30 mins to clear, and on top of that, the bus couldn't shift from 1st gear. (Other than park, netural, and reverse.)
When we got to the school our lunch lady made us hot chocolate and we watched a movie. :D!
I love my school
