What do Storm Troopers, and your household vacuum have to do with each other? Storm Trooper costume armor was made (and can be made) using Vacuum Forming.
What is vacuume forming? This…
Isn’t that the coolest thing you’ve seen all week? But wait! There’s more! Vacuum forming can be done for small things, or HUGE things. Plastic hunting boats are made by vacuum forming a sheet of plastic into the hull. I first saw these about 8 years ago, and at the time, the only DIY one I had seen was large, and would cost $500+ to build. But! My wife and I are going to build a construction toy table (a table for playing with legos / erectors / and k’nex). And, we need some special sized bins, that I’m having a hard time finding for cheap. Then, I remembered vacuum forming, and did a quick search. Low and behold! You can build one for about $20! Using your oven to heat the plastic instead of a special heating element. Yay!!!!
Here’s some more machines for your viewing pleasure.
From all the video’s I’ve watched, and websites I’ve read, people have successfully vacuum formed lots of plastics. My guess is almost any plastic, but the ones I have read about are ABS, PVC, Acrylic, Poly(something or other).
So, here’s a few videos that show some home made vacuum formers. A thorough build is shown in the last video, which is from make magazine video, although I HATE their staples… CHEAP! I prefer this one:
It’s really long, only the first 4 minutes or so are good.
By putting a piece of window screen over the pegboard, and turning the vacuum on before you put the plastic down, you get a better forming, with more details.
We spent New Years in Portland and Seattle with Katrina’s family this year. One of the things we did, is a little glass blowing at Tacoma Glass Blowing Studio. It was AWESOME!!! If you are ever in Tacoma, you should definitely do this! There is probably a glass blowing studio near you that may offer something like this as well. Definitely worth the money.
They are kept hot because glass doesn’t stick to cold things.
This is interesting, they cool the outside, to ensure that the walls of the glass are consistent. By adjusting the heat in different places, they can vary the way the bubble will expand in the glass.
He blows into the tube, and then places his thumb over the hole. The heat in the piece, and in the pipe cause the air to expand, and force the bubble into the piece when it’s small (which is hard, just like starting to blow up a balloon.
More glass is added before enlarging the piece further
The blow tube gets really hot since it goes in and out of the furnace and glory hole repeatedly. So it is cooled every now and then with this simple machine.
That is a stack of wet newspaper he is using to shape and cool the body.
He actually did this in three places around the tube, but I only got the last one.
He had to hit this one harder than the others. With them, it was one very light tap on the blow tube, and the piece broke free.
I received an email from “change.org” (see below) that was titled “Action Alert!” and talked about how we need to Tell Obama to push for fixing climate change so that another Hurricane Katrina doesn’t happen. I was appalled. I thought there was no evidence to substantiate what they wrote at all… I even put together this graph, and wrote this post about how their was no evidence. Then, right before clicking post, I played with the graph, and realized, CRAP, there does appear to be a slight correlation. Because I hate how some poeple only cite the stuff in their favor, I decided to post this anyways. But… I still have yet to see any evidence or proof that Carbon capping is the way to fix the problem. Not saying there isn’t any, but I havn’t seen it.
I used the following sites to get this information.
Hurricanes per year came from the NOAA, it is actually Atlantic hurricanes per year.
Temperature Deviation From The Average over the last century came from NASA here.
Because I want to be fair, I explored the data, and tried to find a correlation. I added the column “Average Cyclonic Energy per Hurricane” to the graph by dividing the Accumulated cyclonic energy on the NOAA’s site by the number of hurricanes.
Acculumated Cyclonic Energy is defined on the NOAA’s site as: An index that combines the numbers of systems, how long they existed and how intense they became. It is calculated by squaring the maximum sustained surface wind in the system every six hours and summing it up for the season. It is expressed in 104 kt2.
Tell Obama that One Hurricane Katrina Was Enough
Dear Joey,
Four years ago this Saturday, Hurricane Katrina hit the city of New Orleans with devastating force. None of us will ever forget the heartbreaking images of residents fighting for their lives while their iconic city drowned and our leaders failed to act.
President Bush’s short-term failures compounded the suffering along the Gulf Coast in those fateful days. But his dismal failure to lead on global warming has made extreme weather events like Katrina more likely in the future.
We can’t settle for a world where Katrina becomes the “new normal” of our weather patterns. Our new President has an opportunity to succeed where the last one failed.
Tell President Obama to lead on climate change by pushing for a strong clean energy and climate bill this year >
President Obama led boldly when he pushed through Congress an economic recovery bill that included $87 billion in clean energy investments.
We need that same leadership from him when senators go back to Washington this fall and start working again on energy and climate.
Tell the President to lead by pushing the Senate for a strong clean energy bill >
As we remember the victims of Hurricane Katrina this week, let’s work tirelessly to prevent a future where disasters like Katrina become the norm. A strong clean energy bill is critical to preventing such a future, but we need our President to lead Congress where it needs to go. Tell President Obama to push Congress for bold action today.
Thanks for lending your voice,

Just how much can a Toyota PU take? Being submerged? Fire? Dropped?
So, if you haven’t heard, two satellites collided a few weeks ago. What is interesting to note, is exactly how much energy was involved… When you think of these satellites colliding, you may imagine two cars just kind of running into each other at a stoplight… This is not the case. Imagine the damage inflicted when you shoot something with a high power hunting rifle…
Note, I do not agree with this video’s creators message, that banning guns will stop the bullets. But the slow motion footage, is SWEET!
httpv://www.youtube.com/watch?v=emP5D9Klssg
It will pretty much go through anything short of 1/2″ steel. Now, Scale that up, so the bullet weighs about 1,000 lbs, instead of a few ounces… That would be a pretty devastating weapon right? But we aren’t through yet, now, increase the speed of this VW van sized projectile by a factor of about 20… Yup… 20 times the velocity of a speeding bullet… Now crash two of these hypersonic VW’s together at right angles… And you get something like this:
httpv://www.youtube.com/watch?v=JyG3zqLyW8k
Which, quite frankly, (all the negative consequences aside) is pretty freakin awesome. Atleast it makes for a cool video.
How about compared to the Army’s High Energy Kinetic Rounds (Depleted Uranium Sabots)? They weigh about 41 lbs (24 times less) and travel about 4000MPH (about 1/5th the speed of the satellites that collided).
This is the simple, yet hard secret to financial success: SNL: Don’t Buy Stuff You Can’t Afford
“We’ve even taken out loans to help make payments.”
“If you don’t have any money, you should not buy anything.”
“There’s a whole section here on How to buy expensive things with money you’ve saved”
“And where do you get this ‘saved money’?”
So… My wife forwarded this list to me. It presents an old issue in a different perspective through humor.
Those who hammer their guns into plows will plow for those who do not.
