It’s only day 2 but the questions keep coming! Over 35 live chats and hundreds more great questions.
Today’s highlights in the Extreme Speed Zone:
- Tarbert Academy students offer Sam a job (sort of)…
archiandlaura : would you like to work as a physics teacher in Tarbert Academy?
samgeen : Ha, maybe if I get bored of research I could be a teacher!
aaronjohnstone : we have a very interesting school! no getting bored here
- We learn why our ears pop:
kirstyi : Why does popping your ears help withstand pressure?
samgeen : Pressure differences happen when the air inside your ear is higher or lower than the air outside – popping your ears causes the air to mix, and the pressure to become the same
- And how much does data weigh?
jamesagrear : If you have a full memory stick and an empty one, will the full one weigh more?
robertwoolfson : A full memory stick won’t weigh more, but it will contain more energy as information is a form of energy. The full memory stick will be less stable than the empty one
jamesagrear : but dont trapped electrons have a mass?
robertwoolfson : An empty memory stick has the same number of electrons, they’re just more disordered
jamesagrear : check this link out 
robertwoolfson : You learn something every day. Wow, I did not expect that. I guess that makes sense as information is energy and energy is a form of mass.
