HOW-TO: Make your own super last-minute superhero costume for our Comic-Con Mixers & Elixirs

Need a last-minute costume for our Comic-Con mixer on July 18? No problem! As a connoisseur of procrastination myself, I know that waiting until the last minute to prepare a costume can be as stressful as it is a unique and beautiful catalyst for creating stunning, creative accoutrements.

Copy Man surveying the landscape, forever on the search for those who need rescuing from copy-related emergencies.

Here’s a simple way to create your own bare bones superhero costume:

SUPPLIES

  1. Regular clothes
  2. Underwear (that can fit over your outerwear)
  3. A large swath of fabric
  4. Paper
  5. String
  6. Markers

PROCESS

Step 1: Pick a super-identity.
I chose “Copy Man” because I’m a copywriter.

Step 2: Pick out clothes that fit your super-identity.
I picked what I wore today to work … because I’m a copy writer.

Step 3: Put on clothes from step two.
Already on!

Step 4: Put underwear over clothes (bonus points if they also fit your super-identity or are really cute).
Sorry, if I had thought about this step before I left the house I would’ve worn cuter underwear.

Step 5: Find large piece of fabric and drape it over your shoulders.
Instant cape! Mine’s made from a curtain, fixed together with earbuds.

Step 6: Make a mask out of the paper and string.
Feel free to color yours in, but I wanted a more monotone palette.

Step 7: Draw a symbol on a piece of paper to represent your super-identity.
CM = Copy Man!

Step 8: Affix symbol to your shirt.
Tape is a beautiful invention.

Bonus step: Create awesome headgear or props with more paper and/or other found objects.

TA-DA! DONE. This took me, like, 15 minutes to put together, so if a friend of yours tries to come up with excuses on how they don’t have time to put a costume together before our Comic-Con Mixer at 7 p.m. on Friday July 18, tell them, “NO EXCUSES!”*

*You don’t have to wear a costume, but they are encouraged! See you Friday!

Copy Man was just a mild mannered copywriter until one day the Houston Museum of Natural Science decided to throw a Comic-Con party.

Educator How-To: Build your own personal hovercraft

A hovercraft may look like some high-tech alien vehicle, but the concepts behind its inner workings are really quite simple. Building a hovercraft is an excellent way to investigate the principles of air pressure, friction, lift, thrust, and drag and serves as an excellent motivator for hands-on discovery — for even the most reluctant of learners.

A hovercraft is an ACV (air cushion vehicle) that rides on a pillow of slightly pressurized air. The hovercraft sports a skirt around its perimeter designed to contain air generated by a fan, or in the case of our craft, a repurposed leaf blower.

Build your own hovercraft!The air contained by the skirt in turn creates a cushion that lifts the hovercraft a small distance off the ground. Note: The weight a hovercraft can lift is easily calculated by multiplying the cushion pressure by the area of the craft.

Once lift is achieved, the craft uses directed air to create a forward thrust, allowing the vehicle to be forwardly mobile. A typical hovercraft creates this forward thrust using a propeller or propellers that push air toward the back of the vehicle. Using the principles of lift and thrust, as explained above, the hovercraft operates much like an airplane.

Build your own hovercraft!Now that the craft has forward momentum, it must be steered. Steering is achieved in various ways, depending on vehicle design. A system of rudders placed behind the fan may be used to direct air in different directions, allowing the vehicle the freedom to turn.  This configuration is similar to the mechanism used to steer some boats. Other hovercrafts use subtle shifts in the operator’s body weight to steer, a skill that takes practice to master.

The Museum’s simplified hovercraft was constructed by our own Carolyn Leap using a collection of ideas with a few modifications:

•    Rounded off corners on a square of plywood in order to reduce the weight of the vehicle – a circle of plywood is an even better option for reducing weight.
•    We sought help from the Exhibits Department to cut a hole to accommodate an unusually shaped leaf-blower outlet.
•    We used a plastic tablecloth completely reinforced with duct tape because the plastic seemed inadequate on its own.
•    Reinforced the skirt’s attachment by stapling AND taping around the edges.
•    Added pool noodles (split along one side) instead of pipe insulation as a bumper
•    Added duct tape flaps (sticky sides together) and attached them around the perimeter of the nozzle to create a more effective seal to improve lift.

This hovercraft is used in the Museum’s Xplorations Summer Camp Programs to illustrate various physics concepts. Our hovercraft does not create its own forward thrust and has no steering mechanism, so the craft and rider are guided by the instructor. Take a look at the fun pictures of one of our campers, Noah, as he rides on a pillow of pressurized air!

So here’s what went down after you logged off.

National Geographic has beautiful photos of the Abrolhos Reef, off the coast of Brazil – which scientists have recently discovered is twice as large as previously thought.

The Maker Faire is coming to Austin. According to the organizers, it’s “a newfangled fair that brings together science, art, craft and engineering plus green, food and music in a fun, energized, and exciting public forum.” Will you enter? Tell us what you’re making!

Ohhh…I see. When you said “lucky” what you really meant was “carcinogenic.”
