Emergency Coffee Maker





Introduction: Emergency Coffee Maker

An easy to make drip coffee maker at no cost.
Some times you really need a cup of coffee and there is not an ordinary drip coffee maker at hand (e.g. traveling, coffee maker broke down, etc.). There is a simple solution. Just take an empty plastic bottle of soft drink and cut it in two pieces. Put the paper filter gently in the funnel part. Next put it on the top of the other part. Add coffee and start purring hot water gradually. In a few minutes your fresh coffee is ready!

Step 1: Choosing and Cutting the Plastic Bottle.

Most of the plastic bottles used for drinks can withstand temperatures up to 90 degrees of Celcius so they are proper. I have tried bottles from carbonated soft drinks with no problem.

Choose the size of the bottle according to the size of the paper filter available and the quantity of the coffee you need.

Make sure that the bottle is clean inside by rinsing it with water.

Use a sharp knife or scissors to cut the bottle. Try to cut it at a position so as the funnel you create will not fall in the other part when you put it on. In case there is not a neck in the bottle, deform the funnel slightly in order to prevent it from falling in the other part.

Step 2: Preparing Coffee

Put the paper filter gently in the funnel so as it will not fold when you start purring water.

Add the quantity of the coffee required and press it slightly without tearing the base of the paper filter.

Start purring hot water gradually. Make sure that the quantity of the water you add matches the quantity of the coffee.

Wait for all the water to pass the filter and enjoy your coffee!

    Hot water and plastics made for a potentially poisonous mix. I would suggest using a tall glass or ceramic cup in place of the PET bottle.

    I can not assure you that this is the healthier way to make coffee but: 1) Ordinary drip coffee maker are made mostly from plastic and water comes in contact with the plastic in much higher temperatures. 2) This is an emergency coffee maker not one to use every day.


    You stole the idea from me, i just took all the pictures and was about to write it when i decided to check for others, and i think your the only one i'm posting anyway

    thanks srry if its hard to understand let me try to clearify I thought of doing that for the contest actually ut wanted to see if anyone already did, thank goodness your good 'ible isnt in

    Nice! it works great, but if your water is too hot, then you risk melting the emergency coffee maker! When i am camping, i add the coffee directly to the thermos, add boiling water, and some nutmeg.

    if you get your water to hot then it wrecks the coffee.

    It is really difficult to melt it! Bottles used for cola ,etc. can withstand the temperatures of coffee making.

    Its a really good idea. But when plastic is heated it releases a chemical called Bisphenol A (BPA). This can affect the body's natural hormonal messaging system. Some studies show that even after ten years of use plastic bottles can still release the same amount of BPA. Bottles made from PETE/PET or 1 Can leech out DEHP ( a human carcinogen) The best choices for bottles would be 2 (LDPE-Low Density Polyethylene) and 4 (PP-Polypropylene). Not trying to scare anyone but I mean the amount of cancer thats been going around has practically doubled in the last decade. But then again I'm nervous being around the microwave......

    Isn't that what led to the "Drinking out of the same bottle of water twice will make you grow breasts!" scare?

    Dole sparkler bottles are great for this

    I've got an even emergency-er one- 1)take handful of coffee beans 2)place in mouth. chew thoroughly. 3)fill mouth up with hot/warm/lukewarm/cold water. 4)wait. 5)swallow. 6)rinse and repeat if necessary. really good instructable though! +1

    brilliant. just did this, gotta stay up to finish the college homework. great idea. thanks for the idea.

    I use another ,even simpler emergency method : I take the coffee beans ,put them directly into the coffee cup.Then pour the water directly onto them.You have to wait about 2 to 3 minutes for all the grinds to settle to the bottom.And sure enough ,it tastes like any normal cup of coffee.Please BEWARE -don't finish drinking the cup completely to the end, since you'll end up ingesting the grinds as you get closer to the bottom of the cup

    Dude. So you're definitely my new hero. Coffee addict with no coffeemaker at the moment, which is the cause of much woe and sadness. Am definitely gonna do this tomorrow morning! <3


    It is also possible to use toilet paper as a filter. Or kitchen paper. Watch out for perfumed versions though.
