School

Tomorrow is in Viet Nam teacher's day. That means, all kids have a day off, go to the teachers house and thank them for beeing there and teach... It's a nice tradition i think, where it comes from and which other countries do that i unfortunately don't know, maybe i can find out. 

Sorry for bad quality...
In front of a Kindergarten or a school it looks always like this... Parents picking up there kids with motorbikes... Reminds me always of a penguin colony and I wonder how they find each other!

I don't know how those things get to my friends and then to me...but these kind of things are worth sharing...

Bonus Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools when it expands and heats when it is compressed) or some variant.

Sometimes you just feel like this...
