Spiderman Tech - How could Spiderman climb walls?

Have you wondered how Spiderman can climb walls?

Let's look at how spiders can climb walls.  Spiders have claws on all of their 8 legs, which enable them to grasp onto the walls or other surfaces.  But Spiderman seems to have tiny hairs that help him climb to the top of a tall building.  These hairs create electrostatic forces (Van der Waals forces)

Van Der Waals forces, causes the hairs on the spider's feet to interact with surface on the molecular level. These hairs are very similar to spikes on the boots that ice climbers use to climb glaciers.  Except that the hairs on the spider's feet interact with the actual atoms on the wall's surface which help to generate forces that hold them onto the wall.  

For a more in depth explanation of Van Der Waals forces, check out the Khan Academy.

Scientists are also working on molecular type of Velcro which could allow humans to walk on walls like spiders do.  With enough tiny hairs in a piece of fabric, this material could be used to help astronauts move around in space or move large pieces of equipment.

Spiderman Tech - What is 'Spider-sense"?

Spider-sense - what does this look like? Would the world around you go in slow motion or is it like a radar that would permit additional reaction time to sense motion around you? How would it help Spiderman detect danger on the horizon? Do real spiders actually have a 'spider-sense"?

This could be explained through a spider's ability to sense vibrations and changes in air pressure. Spiders can feel things approaching be sensing changes in the environment. Maybe Spiderman can sense these changes through the use of trichobothria (a really fine hair that can perceive air currents and vibrations).

Spiderman Tech - Could a human spin a web like a spider?

One of Spiderman's greatest tools are is web shooters.  How did these develop in the comic books and are they scientifically possible?  Find out how his abilities could be similar to Silly String!   (Start video at 3:30 to end) 

1. How strong and elastic is drag line silk?  
2. Spiders can lift great weights, which could be explained by their unique body structure.  How could Spiderman's super strength be explained through science?   Let's consider endorphins (pain-killing molecules that help humans perform incredible acts of strength under stress).  When you have an endorphin rush, you don't feel much pain.  (Start at 5:30)

Can genetic engineering explain Peter Parker's / Spiderman's origins?

Spiderman has spider strength, spider strength and web shooting... and the ability to defy gravity!  How does Spiderman's powers hold up to scientific fact?  Which ones can be scientifically backed up, and which ones are pure science fiction?

Peter Parker gained his abilities after getting bit by a radioactive spider.  How much of this origin story could really happen?  Start the first video below at 3:40 to find out.

1. If an irradiated spider bites a person, will it transfer its radiation to the human?  
2. How might it be explained by genetic engineering?  

 

1. Transferring traits from one organism to another at the stage of inception is one things but...  is it possible to genetically modify a nearly grown man like Peter Parker?  The answer might be found in retroviruses (such as HIV) 
2. How could the genetic information passed along also help Peter Parker climb walls, shoot webs, and have the proportional strength of a spider?   (Beginning of video through 3:30)

Superhero Science in the News

A team of chemical engineers at Cornell have created a palm-sized device that could one day turn troops into human wall crawlers, using an adhesive bond inspired by beetles.

Soldiers can’t leap tall buildings in a single bound, yet. Seeing through walls — that’s a different story. Later this year, American troops fighting in Afghanistan will begin to get gadgets designed to peer inside buildings and detect the heartbeat of people buried under rubble. It’s not exactly Superman’s x-ray vision. But it’s not that far way from it, either.

How do tarantulas walk on walls?

It is a question scientists have long wanted to answer, why is it that large and heavy spiders like tarantulas are able to anchor themselves to slippery vertical surfaces without falling?

A team from Newcastle University have found the answer and the discovery helps explain how spiders first evolved their silk-spinning abilities.

Bulletproof Skin??? Can we make a bulletproof human?

Scientists have created bulletproof skin by using spider silk... Actually, it's created using Spider Goats - goats that have genetically modified to have spider DNA in their milk. Believe it!

Could genetically modified silk someday make humans bulletproof? It's not pure science-fiction fantasy

Silk — one of the strongest natural materials known — has a long history of use in combat: Legend has it that Genghis Khan once issued tightly woven silk vests to his horsemen as protection against their enemies' arrows. Researchers have now taken silk one step further, and developed a fabric made of silk proteins that is strong enough to stop a bullet. Their ultimate goal: To give a person a layer of bulletproof skin. Here, a brief guide to this breakthrough:
