## 10. You can out run a lava flow … USA UNITS

November 17, 2018

This is a rework of a previous post with full calcs.

Every volcano disaster movie from Volcano (1997) with Tommy Lee Jones to Dante’s Peak (1997) with Pierce Brosnan someone somewhere tries to out run a lava flow. Is this possible?

The answer is maybe. You will find everything you want to know about lava flows here.

On January 10,1977, at Nyiragongo lava sprang from the sides of the volcano moving at speeds up to 40 miles per hour. About 70 people were killed.

The fastest Lava flows recorded were in Hawaiiin 1950 when Mauna Loa erupted. The lava traveled at 6 miles per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 60 mph.

Speed of average sprinter = 10 – 15 mph

Speed of average sprinter = 16 – 24 kph

## 3. Chewing Gum Stays in your stomach for 7 years

July 9, 2013

According to How Stuff Works

Pediatric gastroenterologist David Milov told the magazine Scientific American that he can say “with complete certainty” that gum does not stay in you for seven years.

You will find more than you ever wanted to know about the structure of chewing gum (It’s a rubber-based substance though now mostly synthetic) and it’s digestion at the above website and here.

Sometimes, it feels like chewing gum will stay on your shoe for 7 years!!

# Chewing Gum Stays in your stomach for 7 years Myth BUSTED.

## Can’t those scientists count?

…….……..……

According to Shamini Bundell on Null Hypothesis

.....

….Various experts have tried counting the muscles involved. Mainly they argue over how to define a smile and a frown and come up with different answers.

Either way most of the numbers quoted at you by irritatingly cheerful people are entirely made up.

As Shamini noted “It takes 37 muscles to frown and 22 to smile, but it only takes 4 to reach out and punch someone in the face.”

# 43 muscles to smile myth and nose busted.
