Design Proposal

I have chosen the third idea - a vessel that cools coffee down and continues the performance part of the siphon method. I have decided that the design needs to look similar to the equipment already used, so it will be made out of glass. The product will look like a decanter with a spiral tube built inside so the coffee can be poured into and then slowly pass through it to cool down. I think this will be entertaining for people to watch and this presents a new development to tie into the third wave.

Things I still need to do: 

• measure how long the coffee takes to cool down 
• test how long the tube needs to be
• call chem glass to see if they can make it
• get tubing to experiment with 

Here are some sketches
