INTRODUCTION: Water Pack is known to be a portable cooler that you can bring anywhere you go. This is because with other coolers you are not able to bring it on certain types of material. To overcome this problem, we decided to make a cooler in a form of a backpack. One more problem is that it is not always easy for you to get the correct amount of water that you wish for. So we also decided to attach a pump so you can get the correct amount of your beverage of choice. METHOLOGY: First of all we have to cut some polystyrene into the correct measurements and size to fit into a bag. Next we have to glue all the polystyrene into one piece. Once we were done with that, we continue with covering the outer part of the piece with some plastic, then we are going to glue the piece into the bag so your beverage will stay cold of longer. Now moving on to the pump, first we will connect a battery to some wires witch we will be connected to a pump, then on the other end of the battery we will be connected it to a switch to turn it on and off. Next we are going to drill two holes into a bottle cap, next we will connect a rubber tube to the pump and into one of the holes, then we are going to put another rubber tube into the other hole, next we will cut a hole in the bag to put that rubber tube through it, so when you turn on the switch its going to activate the pump witch is going to pump air into the bottle, and with that air pressure its going to force out the liquid out the other rubber tube pouring the liquid out into your cup so you can enjoy your beverage.
Key Word: easy anytime anywhere
