If you don't have any pieces of Styrofoam either go to an electronics store & ask them if they have any or, you can buy a piece of foam insulation for around $5 at any Home depot store. It comes in many thickness all are under $7, the thin ones are only $3... Next, cut these to the size you prefer, then glue together & *PRESTO* you have a mini ice cooler! ... If you need a lid, then carve the top foam to fit into the bottom sections.... Another idea for foam is to glue together pieces of foam board until it's the thickness you need (Dollar Tree sells sheets of it). To make you homemade cooler REALLY work, add aluminum foil to the inside & outside of the foam. ------------------------------------------------------------------------------------------------------------------------------- SECOND IDEA: if its not a school project, but you just need to keep things cool in the car or on a short trip whatever: You are gonna think I'm nuts... But I like to take frozen treats with me on long drives during the hot months & I use the arms cut off of wool sweaters... Put one or 2 inside of the other one & put your stuff in a bag & put it inside... To do this the right way, add 2 of those blue cooling blocks or re-freezing gel after you've put your stuff in the wool sweater sleeves, put one blue-ice thing on one side & one on the other. I've had frozen yogurt & frozen mango chunks stay frozen for several hours this way. Popcycles will stay frozen about an hour. Lastly you can wrap the sleves inside of the rest of the sweaters. (the body of the wool sweater) * The theory is: If something can keep you warm, it can also keep you cool. When I bring home frozen stuff, I'll wrap the bags up with one or 2 of my winter coats for added insulation.

Katie from Miami RE: Homemade Thermos Get a small box that is just a bit larger than your soup container. Wrap the soup container with aluminum foil with the shiny side in (facing the container) and place the container inside the box. Add Styrofoam packing peanuts to fill in the empty spaces that surround the container. Styrofoam is a pretty good insulator; it should help to retain heat in the soup. The aluminum foil's shiny side will help to reflect the radiant heat released by the hot soup back into the container. I have always been a hoarder of packing materials and small boxes and pick them up at work from the trash heap. These items usually lurk near trash cans behind stores, if you don't have access to them at a place of work. Another method would be to use expanding foam to fill the empty spaces between the box and the soup container. See this website for a DIY project where a guy made a homemade thermal carafe: http://www.thinkythings.org/carafe/build.html You could use another bowl that is larger than your soup bowl for the outside container. Good luck (01/23/2007) By P. RE: Homemade Thermos Another thing to use is foam peanuts and paint both containers with black/dark paint. (10/12/2007) By Sarah from New York RE: Homemade Thermos Using a rubber material or reflectors would slow down the process of cooling the liquid. (10/17/2007) By kahunstin RE: Homemade Thermos Great way to make a thermos: I would suggest to use a lot of aluminum foil this way it reflects. This is great for people trying to keep things cold. It actually made my experiment colder. All you need is the foundation. (04/21/2008) By mike Report Spam or Abuse
