According to Heinz Company's website, every year, Heinz Ketchup sells 650 million bottles of ketchup across the globe, and each batch is tested to ensure that it pours at the proper speed. Ketchup exits the iconic glass bottle at .028 miles per hour.

"If the viscosity of the ketchup is greater than this speed, the ketchup is rejected for sale,” according to the company's website. What's the best way to get Heinz ketchup out of the iconic glass bottle? According to the website, "To release ketchup faster from the glass bottle, apply a firm tap to the sweet spot on the neck of the bottle -- the '57.'"
