Science Experment

Today in maths we learnt physics.We set a tea bag on fire and it somehow flew into the air.
We managed to figure out how it worked.As we set the top on fire it slowly burned to the bottom.
Before the fire it went out, it blasted into the air. The reason for this was because the heat from the fire
caused the air from inside the tea bag to heat up.So the tea bag flew up because heat rises.The air inside the tea bag was hotter then the air outside the tea bag.

The cold air is also more dense.This means that the particles are closer together and and they have less energy then hot air and that is why it made the tea bag fly.

DMIC FLIGHT WORKOUT

I know New Zealand is 1 day and 1 hour in front of London and we left on Tuesday.

i also know it takes 8 hours to get to Hong Kong from Auckland and they stooped for 2 hours so that the day is Wednesday

i also know that is takes 5 hours and 55 minuets to get to London from Hong Kong and then the time is 4:55

so 5 hours + 8 hours = 13 hour + 55 so it is 13 hours and 55 minuets

so you arrived in London at 6 pm Auckland time
and arrived on Tuesday at 5 pm London time because London is 13 hours behind Auckland time

and that is how i worked my dmic question
