In part 1 our questions include: 02:18 How can I make alcohol easily at home? 05:36 Why did chemists believe Mendeleev? 11:52 What is the air speed of an unladen swallow? 12:15 Why is an octopus so squishy it can fit under a door? 15:04 Someone’s homework about pollution but also why ‘useless’ lessons are so useful 20:32 Can we really call subatomic particles ‘fundamental’? 24:10 Why do opposite charges attract and like charges repel?, and 28:14 When is a chemical bond not really a bond?

Make sure you subscribe for part 2 and other ‘Hit Me with Your Questions’ videos. If you have any questions you’d like me to answer for next time, just post them in the comments section. If you want a bit more explanation, or if you can explain something better, put that in the comments too.
