Cool Water Cooler

The summers are getting warmer and a way to cool yourself and at the same time hydrate is to drink cold water.

I use to take empty PET-bottles and fill them 1/3 with water an then put them in them freezer. When I need some really cold water I take one out an fill it up with cold water. The ice will cool the water for a while.

This summer i was disapointed about the ice melting too fast so I made a small cooler for my bottle. I had some scrap insulation foam and duct-tape. The ice lasts for hours now. I will show you my way of making one for you water bottles.

You can take any size of bottle, make shure you have at least one extra so you hav one in the freezer while using the other. Using thicker foam and aluminium tape will make the ice last longer. Braking the ice in the bottle will make the water cooler faster but it will melt faster.

You will need a sharp knife or sissors. Optional is a speed square and a ruler. For the insulation you can use a discarded camping matress och some other plastic foam. I use duct-tape to bind it together but you can also use a glue gun.

So I measured the foam by rolling it around my bottle. Give it a little extra so the bottle don't get stuck. I placed a piece of tape on the inside and then on the outside of the joint. I tested my bottle to make shure it fits. The tape I used is a special tape that sticks very well. There is no real need for that. Make it a little bit taller than the start of the bottle neck. That makes it easier to fit the top cap.

I made a round piece to fit my bottles bottom. Cutting with sissors is the best way. I found a roll of tape that was right for my bottom. Mark it with a pen and cut. I taped it to my cooler.

I taped the whole cooler with duct-tape for durabillity. I use it while building my house extension.

I made a top cap the same way i made the bottom and taped the top with duct-tape. One piece of tape per turn.

Then I cut a fairly round hole to fit over the neck of the bottle. As you can se it is tucked in the top of the coller to make a snugg fit.

Put some bottles in the freezer with 1/3 water. Half laying down or the ice will plugg the hole.

When frozen, fill with water, put it in the cooler and shake it to do a fast cooling. The ice will last for 2 - 3 hours or more depending on how much you refill it. It last a lot longer than without the cooler.
