Intro: Need a Funnel in a Hurry?
Sooner or later you will find yourself saying something like "this would be so much easier/faster, if I only had a funnel." Well here ya go, the quickest, easiest and probably cheapest way to make a funnel for liquids. It's so easy, you could be done by now.
Step 1: Materials
You will need.
A plastic bottle I like 2 liters because they are wide bottles with narrow necks. but any old bottle will work.
A knife, razor blade is probably best but if it's sharp it'll work
Step 2: Stab, Slice, Chop, Cut
Cut the top off of the bottle. below the shoulder is best because it makes for the strongest and widest funnel given our nearly nothing budget.
Step 3: Rinse and Use
If your funnel is going to be used for anything except the bottle's original contents you should rinse it before use. enjoy.
