This is a drip coffee maker that uses the Red Bull can as the main component. The Red bull can was cut in half and the bottom was hammerd to a cone on the bottom. A hole was poked on the bottom of the funnel and the sharp edges of the cut section of the can taped. Using a coffee filter and rubber ban to hold it place allows you to place coffee grounds in the filter and poor hot water to make some great coffee. The rendition you see on this photo is the smaller version then the one uploaded as my printer build space was too small to print the full version.
