Scientific Lifehack: How to Empty Ketchup and Other Plastic Bottles Completely

Don't you just hate it when you have to throw away ketchup bottles that still have just a little ketchup left in them? Getting that last little bit of ketchup (or any other product) out of a bottle can be nearly impossible – until now.

The key to emptying those bottles is centrifugal force which simply means that you have to know how to swing your bottles to get all of the product to the top so that you can easily empty them.

This little trick works perfectly with ketchup, salad dressings, mustard and practically any other condiment type bottle you may have in the fridge.

So, instead of throwing out those not quite empty bottles (and instead of leaving them in the fridge for months because you simply cannot seem to throw them out while they still have something left in them) learn the proper way to swing the bottle so that all that ketchup runs to the top. You can empty it, throw it away and replace it with a full bottle.
