Sustainability is an asset. Reuse too. And a former yogurt bottle after drinking the right or left-handed sludge is very suitable for using a few pieces of hose:
* To make a nice buffer bottle in the 'discharge line' of the battery
* To be used as a lever when emptying - for example - a brake fluid jar with your mouth
Just look at the picture for how simple it is and note the difference in level of the tubes in the bottle
