Use the Balloon As a Pouring Device Without Spilling Liquid
Some liquids, such as engine oil, can be difficult to pour, especially if they are in heavy, unruly containers. A balloon can slow things down and make sure you don’t make a mess.
We’ve covered some of the balloon tricks before, but this video from YouTube’s MAD Science Hacks showcases a lot more, including how to make a spout without a spill. Just take a balloon and snap it onto the neck of the container, make a small slot on the other end of the balloon, and fill. Precise pouring without funnel and without spills.
