Welcome! Today, we’re diving into some common misconceptions about dangerous situations. Let’s clear up these myths and learn some important facts!
Many people think quicksand is a major danger, but it’s not as scary as it seems. A study in the journal Nature found that humans can’t completely sink in quicksand. Our bodies are too light to sink all the way down. Even if you struggle, you’ll likely only sink up to your waist. If you stay calm, you’ll float back to the top.
If you ever get impaled by an object, don’t pull it out! It’s best to leave it in and call for emergency help. According to Dr. David Biser, removing the object could cause severe bleeding because it might be blocking a hole in an artery or vein.
Some people think you can get water from a cactus, but that’s not true. The inside of a cactus contains toxic substances that can make you sick, causing vomiting or diarrhea. This would only make dehydration worse.
Drinking urine might seem like a survival tactic, but it’s not a good idea. Urine contains waste that your body is trying to get rid of. Drinking it can lead to kidney problems if done repeatedly.
Using an umbrella to slow a fall might sound like a fun idea, but it doesn’t work. In 2013, a skier tried skydiving with an umbrella, and it quickly became useless. An umbrella can’t support your weight or slow you down significantly.
Many people feel safer from fires at home, but most fire-related deaths happen in residential areas. In 2011, there were about 2,500 deaths in home fires compared to around 100 in non-residential buildings. It’s important to have fire safety measures in place at home.
Tornadoes can happen in any season, including winter. For example, a major tornado outbreak occurred in February 2008, affecting several states in the Southern U.S. Winter tornadoes can be especially dangerous because they often move faster.
Jumping in a falling elevator won’t save you. You’d need perfect timing, and even then, you’d only reduce your impact speed by a small amount. Elevators usually fall at around 50 mph, so jumping won’t make much difference.
How you react to a bear attack depends on the type of bear. For grizzly bears, playing dead can be effective because they are usually defensive. However, black bears are often predatory, so it’s better to drop any food and back away slowly. If a black bear approaches, act aggressively and make noise to scare it off.
Trying to suck out snake venom is not helpful and can be harmful. Dr. Robert Beish advises against cutting or sucking the bite or using a tourniquet. These methods can delay proper medical treatment and cause more harm.
Thanks for learning with us! If you have any topics you’d like us to cover, let us know. See you next time!
Conduct a simple experiment to understand the properties of quicksand. Use a mixture of cornstarch and water to create a non-Newtonian fluid. Observe how objects sink and float in it. Discuss why humans can’t completely sink in real quicksand.
Engage in a role-play activity where you practice responding to an impalement injury. Learn the importance of leaving the object in place and calling for emergency help. Discuss the potential consequences of removing the object.
Participate in a simulation game where you make decisions to survive in a desert environment. Discuss why drinking from a cactus is not safe and explore alternative survival strategies.
Create a fire safety plan for your home. Identify potential fire hazards and discuss the importance of having smoke detectors and an evacuation plan. Compare the risks of fires in residential versus commercial buildings.
Discuss different scenarios involving bear encounters. Learn how to identify grizzly and black bears and practice appropriate responses for each type. Understand the importance of knowing the right actions to take during a bear attack.

Hi, I’m Elliot, and this is Mental Floss on YouTube. Today, I’m going to talk about some misconceptions regarding dangerous situations. So buckle up!
**Misconception #1: You sink in quicksand.** As comedian John Mulaney noted, quicksand is not as big of a problem as we might think. A 2005 study published in the journal *Nature* found that people can’t completely sink in quicksand; we actually float because our bodies are not dense enough to sink in the mixture of sand, clay, and saltwater. Even if someone struggles, the most they will likely sink is waist-deep. If they wait patiently, they should be able to float back to the surface.
**Misconception #2: Pulling out a knife is better than leaving it inside you.** If you get impaled by any object, it’s best to leave it in and call for emergency help. Dr. David Biser, an emergency medicine physician from the University of Chicago Medical Center, has stated that the object may be plugging a hole in an artery or vein, and removing it could lead to severe bleeding.
**Misconception #3: You can drink from a cactus if you’re stranded in the desert.** While some may suggest opening a cactus for water, it’s important to note that the pulp is not actually water. It contains toxic alkaloids that can cause vomiting or diarrhea, which would worsen dehydration.
**Misconception #4: You can drink your own urine if you’re dehydrated.** Some people claim that drinking urine can save you in desperate situations. While it might work for a short time, urine contains waste products that your kidneys are trying to eliminate. Drinking it continuously can lead to kidney failure.
**Misconception #5: An umbrella will slow a big fall.** In 2013, pro skier Eric Roner attempted to skydive with just an umbrella. While it may have slowed him down slightly at first, the umbrella quickly became ineffective.
**Misconception #6: House fires are less likely than fires in commercial buildings.** A survey by the Society of Fire Protection Engineers found that 65% of Americans feel safer from fires at home. However, most fire-related deaths occur in residential settings. In 2011, there were around 2,500 deaths in home fires compared to about 100 in non-residential buildings.
**Misconception #7: There are no tornadoes in winter.** Tornadoes can occur in any season. For example, a notable tornado outbreak happened on February 5th and 6th, 2008, affecting five states in the Southern United States. Tornadoes can be even deadlier in winter because they often move faster.
**Misconception #8: Jumping in a falling elevator will save your life.** The idea that jumping at the moment of impact can save you is misleading. You would need exceptional reaction time and would only reduce your impact speed by about 2 to 3 miles per hour. Falling elevators typically hit the ground at around 50 mph.
**Misconception #9: Always play dead during a bear attack.** How to respond during a bear attack depends on the type of bear. Grizzly bears are usually defensive, and playing dead can be effective. However, black bears tend to be predatory, and in that case, it’s better to drop any food and back away slowly. If the bear approaches, you should act aggressively and make noise.
**Misconception #10: Sucking the poison out of a snakebite will save your life.** According to Dr. Robert Beish, an emergency room physician, cutting and sucking the bite or applying a tourniquet does not help and may cause more harm than good. These outdated methods can delay proper medical care and lead to further complications.
