My little homemade wort chiller. I had about 50' of 3/8 tubing and decided to double the surface area (and halve the length) of the copper by splitting it into two coils. Splitter is just a $5 washing machine hose splitter and the joiner is just a $2 garden hose splitter. Got a deal at Home Depot on the hose because a couple feet had been trimmed off the end, so total cost is about $47.
