The only application that bernoulli's principle applies, is determining the flow rate of the water, and the maximum height of the tube, but it's not why this works. Gravity is why this works.

Or be an ass like my roommate was when he did this and attach the hose directly to the sink via another hose clamp and feed the other end of the hose out a hole he cut in the screen in our window. I don't know why he thought it would be a good idea to do that considering we lived on the 7th floor of our dorm and our window was above the rear entrance.

Anyway, put top on, hole in and hole out, one for fan to blow in and other for some pipe tube say by 3 inches across like, turn fan on, put in ice, air blows in, over cool ice and out other hole, nice, cool. Simple, easy, less water used, use ice bags, so no water either in some cases, or cooler plug in version, simple eh.

Aug 12, 2009 - pretty cool, but i wouldn't want unsightly buckets laying around my dorm...

Aug 13, 2009 - if your dorm doesn't have a/c, it's probably gonna be small and crappy and you wont have room for the buckets. maybe for a storage shed or a hot room with exercise equipment.

Aug 16, 2009 - it's a pig's idea!

Aug 18, 2009 - I'm actually interested in this, not because I live in a shitty dorm, but because I live in a house with shitty insulation.

TheGrilNextStreet Says:

Aug 18, 2009 - so you have to like refill the bucket of water before it runs out and empty the other one constatnly?...

FLICKFIVE Says:

Aug 19, 2009 - Thanks you guys rock I made one for my office using a fish tank water-pump to re circulate the water and Ice in the bucket of water. this works great!

bikerboy6120 Says:

Aug 20, 2009 - niiiice. i am going to do that but with recurculating water. thanks a lot.

Aug 22, 2009 - No AC in my dorm, and i live in Texas. I need this

Aug 27, 2009 - Maybe you didn't take thermodynamics... but you are an idiot.

MattFoleyMotivation Says:

Sep 2, 2009 - It's interesting that you say that you live in Texas and have no a/c because I hear this as a common complaint from people in Texas. I've lived in Texas and I thank God I no longer do because it is a backwards-ass place and even though the people are nice, the state as a whole is a dump.

JordanMaster22 Says:

Sep 20, 2009 - I made this, and trust me. You will need at least 10x more copper coiling than that for it to actually feel cool.

tracker8v Says:

Sep 29, 2009 - you dont pay for water at a dorm do u? why not just hook one end to the sink and the other to a drain?

dimsanda Says:

Oct 31, 2009 - if we wind more coil,can we get a more cooler one for a large area???????
