Everyone hates waiting for anything. We are a very impatient society, so anything that speeds up the process of any part of our lives will be a huge success.

So, I say invent a micro-chiller, the opposite of a microwave. think how awesome it would be to grab your drink and have it cooled in 20 seconds.

it may take some investigation, but I bet it could be done a small scale for your project.

 

Not trying to condescend but you can do this at home with ice and salt! Although people aren't as adventurous as they used to be (i'm only 20 what do i know..)so a device would probably sell....
