Is it possible to make web shooters

In that case, we can find the web volume estimation by a factor of That gives a total volume per hand of 0. What would this look like if it fit around a wrist? If I use my own wrist for a basis, then I find that it has a circumference of In my web container design, I will let the cartridge go back 10 cm along my arm.

Now I can calculate the thickness of this container. Maybe a picture will help. Here is a look at my device looking down the arm. Using the values from my estimates, I get a container radius of 9. Here is what that would look like.

That looks a little awkward. But just imagine how large this thing would be the webs were something like nylon or steel cable instead of nanotube rope.

I already said that it seems like these webs should be able to reach at least a 10 story building about 30 meters. What kind of launch speed would a web need to get this high? Yes, that is obviously not realistic but I will proceed anyway. This is what makes the Internet so great. If a web is launched straight up, there will be only one force on it - the gravitational force.

This constant force will make the vertical velocity decrease as it rises. This will give an average vertical velocity of:. Since the web is slowing down with an acceleration of -g, I can find the total time to get to the top of the building using the definition of the acceleration.

Now I can use the average velocity and this time interval to get an expression for the change in vertical position. And there is your expression for the launch speed of the web. Sure, you could have just used one of the kinematic equations but what fun would that be?

Using a the value for the change in height of 30 meters, the web launch speed would be But wait. What about air resistance. I could use the typical model for air resistance that say the force from air is proportional to the square of the speed:.

Sketch your web shooters in pencil so you can make changes easily if needed. Cut out your design to make a template. Guide your scissors along the lines you just drew, cutting slowly and carefully to avoid mistakes. Use your template to cut 2 identical wrist pieces out of 5mm craft foam. Place the design you just cut out in the center of the sheet of foam and run your pencil lightly around the edges.

Then, remove the paper and cut along the pencil lines to create the same shape out of foam. Repeat the process with a second piece of foam to make the wrist piece for your opposite hand.

If possible, use gray or black foam. You may have trouble getting your scissors through the thick foam. If you encounter a lot of resistance, consider using a utility knife instead. Just be sure to ask your parents before you do! Cut 3 cm 1. The easiest way to do this is to draw a single rectangle on a piece of paper, then cut out the shape and use it as a template for your foam pieces.

The foam rectangles will serve as the wrist straps for your web shooters, so make as many as you need to fit around both wrists comfortably. This will tell you exactly how many you need for each web shooter. Paint your foam pieces if you want them to be a different color. Brush one side of each piece with a coat of acrylic craft paint and allow them to dry for minutes.

Then, flip over the pieces and paint the opposite side. However, you can also add a few accents in red or another color, if you like. Glue your foam pieces together with the wrist pieces in the center. Squeeze a line of hot glue onto the inside edge of one of the end pieces, then press it to the outside edge of the piece next to it. Keep gluing like this all the way down the line, then let the glue dry for about 5 minutes. Attach Velcro to the ends of your completed wrist straps.

Cut 2 soft strips and 2 rough strip to a length of 3 centimetres 1. Dab dots of hot glue onto the back of each strip. Press a strip to the inner face of one of the end pieces and the stick the other to the outer face of the piece on the opposite end.

Do the same for second web shooter. Make sure you get the uncut kind so you can trim it to the correct length yourself. Make sure the Velcro pieces are facing the opposite direction so your web shooters will fasten properly.

Adding Velcro will make it possible to put on and take off your web shooters whenever you want. Cut out 2 keyhole-shaped pieces of 3mm foam for the trigger pieces. This piece will be shaped like a thin rectangle with a circle at one end. This will allow you to bend it into a shape that will better fit your hand. Glue a straw to each wrist piece to make a nozzle for the webbing.

Take your scissors and snip two 1 in 2. Then, cut a rectangular notch at the top of the foam on both of your web shooters just wide enough to fit the straws into. Dab the bottom edge of the straws with glue and slip them inside the notches. Method 2. Cut 5. Mark the pipe in regular increments to indicate where each piece will begin and end. Then, cut it into individual segments using a hacksaw or similar tool. Work slowly and carefully to avoid accidents. Be sure to cut an appropriate number of pieces to bring your preferred design to life.

Spray-paint the pipe segments silver. Stand the pieces up on a sheet of scrap cardboard or newspaper. Shake your spray paint can a few times to make sure the paint is thoroughly mixed, then press and hold the button on the back while waving the nozzle over the PVC in smooth, slow strokes.

Make as many passes as needed to completely coat the pieces. Choose a metallic type of paint to give your web shooters a more realistic finish. Likewise, instead of manually adjusting the nozzle tip of his web shooters, Spidey could later just turn his wrist in key directions to alter the type of webbing he sprayed this latter design was attributed to his clone Ben Reilly, but Peter likely has his own design for changing his web.

Although the web fluid is made in liquid form, it expands and hardens on contact with air, turning into a thin but superhumanly sturdy material when Peter shoots a web. After some time, however, the webbing actually gets weaker and more brittle, eventually dissolving within an hour or two depending on the formula.

Steve Ditko actually drew an entire page showing Spidey reshaping his webs into a club, a raft, and even skis! While Marvel Comics has never given readers an exact formula, there have been several clues over the years.

This could mean that Peter was forced to use chemicals and materials he could buy or order from chemistry shops. In later years, Peter borrowed equipment and chemicals from the fully stocked chemistry labs of Empire State University and greatly improved his web formula.

One humorous Spider-Man prose short story plays up on this by showing Peter Parker picking up some plastic for his web formula at a hobby chemist shop. Fortunately, that crook also shopped at the same chemist shop to buy the helium for his getaway balloon. Peter wondered why no one had ever managed to duplicate his webbing exactly since he designed it in high school — but this might be because a state-of-the-art lab might overlook some cheaper chemicals that Peter needs to use by necessity.

According to her, Spider-Man is a scientific genius who created an astounding web formula.
