Everyone would have faced struggle when trying to get ketchup out of a glass bottle, you might have shaken, whacked, or even used a knife to get the ketchup out of the bottle but all your efforts would have ended in vain. There are many glass ketchup bottle tricks to get your ketchup out faster from any bottle.  

How to Get Ketchup Out of a Glass Bottle

  1. Shake the bottle vigorously with the lid on. This makes the solid particles at the bottom of the jar to mix into the rest of the sauce. 
  2. Turn up the bottle upside down and push downwards at high speed. This moves the ketchup to the neck of the bottle.
  3. This trick works very well if your bottle is nearly empty. Now, remove the lid and turn the bottle upright and pour.

Physics behind It

Ketchup may look like a liquid, but it is a non-Newtonian fluid. It doesn’t flow consistently, It behaves like a solid and a liquid depending on how we shake—the viscosity in these substances changes with the amount of force you put on them. When the bottle is shaken vigorously, the ketchup becomes 1,000 times thinner. That’s why the sauce often ends up like a mountain. 

What Does the 57 Mean in Heinz 57 Ketchup?

Heinz is one of the best-selling ketchup brands and it’s been in the market for nearly 150 years. But in all these years, people find it difficult to get the right amount of ketchup from the bottle. A spokesperson from Heinz says a gentle tap on the 57 on the Heinz bottle will make the ketchup come out easier. Many even think that 57 in Heinz is just for tapping purposes but it’s not. “57” represents the historical advertising slogan of the brand. The founder Henry John Heinz inspired by a shoe advertisement “21 styles of shoes”. Heinz considered number 57 to be lucky and magical so he gave “57 Varieties” as their slogan name although the company offered nearly 60 products at the time. Even today Heinz is known for “57 varieties” though the brand offers 5,700 products.
