how do i make something inflate and deflate on its own on a loop?

I have these homemade latex balloons and I was to make them inflate and deflate on their own continuously? I know I probably need some sort of blower...

Inflatable Animals on NYC Streets

Joshua Allen Harris makes awesome animal sculptures out of plastic bags and places them over subway grates to that they inflate when the gusts of hot air shoot out of them. Here's a video of his newest one as well as a couple of previous animals.

Why do you think there is inflation?

I think there is inflation because people are charging each other more.

Soft toy/inflatable design software

Does anyone know of a way I can design my soft toy/sculpture/inflatable in 3d then print out the parts with software? Otherwise, how should I do this? Appreciate the help!

Just another day at Instructables/Squid Labs with a giant inflatable Tyvek geodesic dome

Here, tetranitrate works on his next boundary-pushing project while menaced by an inflatable Tyvek geodesic dome build by Pete Lynn, of kiteboarding fame, for this year's Burning Man.

Help Build a Giant Inflatable Instructables Robot

Can you keep a secret?For the Austin Maker Faire in October, I'm hoping to build an 8-foot tall inflatable Instructables Robot. I want it to be easy to find the Instructables booth.For his wedding, Saul, built an inflatable elephant using many of the techniques from inflatable kite design and papercraft. There's a lot of CAD work required, and since I know there are some people here much better at Rhino and Blender than me, I'm asking for help. If we can pull it off, you'll get the joy of having something you designed be made very large.Here's the process and where you can help: 1) creating a model of the robot that is appropriate for cutting in fabric, sewing together, and inflating. chooseausername did a brilliant job here, but the model has too many polygons, and just reducing the number of polygons in his model results in something that doesn't quite work.So first, I need a model of the robot that is less than 1000 polygons while still retaining the robot's personality. Also, since it will be inflated, the robot's wheels should be retracted (its legs should just be cylinders of the same height as its legs plus wheels). We can print on the fabric, so the line on its belly doesn't need to be physical, but its buttons, eyes, ears, and antennae should stick out as they normally do; no need for individual fingers. Make sure all the normals point outward in the model.Saul isn't quite ready to share his CAD files, so I've included screenshots of his elephant as an example. The full grey elephant has 1000 polygons. 2) modifying the model to account for real-world limitations and to make it easy to import into Pepakura Designer. As the elephant is symmetrical, Saul cut it in half, split out various body parts -- ensuring that they exactly fit back together on the vertices of the polygons (seam lines for sewing), -- and made some part of the ears a single piece of fabric which would not inflate. In the robot's case, we would probably split the legs, body, head, and ear-and-antennae assemblies. The antennae will probably need to be a slight larger diameter than they normally are. Since the robot isn't symmetric, we'll keep it whole. 3) using Pepekura to create panels4) arranging the panels, adding seam allowances, and sewing instructions.5) repeating steps 1 - 4 to create the bladders for inflation with a model that's slightly bigger than the skin.6) getting a factory to cut and sew everything together.As you can see, step 1 is the most important part. If you'd like to help, create a model of the robot, and add it to a step of the collaboration I've started here (PM me for an invite):https://www.instructables.com/id/ETZ3QJSFKD1LWHU/We definitely have more than one person working, as I'm sure everyone will have something valuable to contribute.If you're interested in other giant inflatable creatures, leave a comment here. If we can streamline this process, we might make a complete zoo!

Glueing Rubber

I'm trying to make a long inflatable rubber tube buy cutting a bike inner tube and then resealing the ends. I'm doing a bit of a trial run with all the suitable materials I have knocking about but I was wondering if anyone has any suggestions. I need it so I can inflate the tube with little or no leakage (not to any great pressure) and I would like it to remain at least semi flexible so that means I cant just pack the last 2 inches with hot glue. Any suggestions? I plan to try poly-cement, epoxy, hot glue, super glue and melting the ends together but I'm sure someone has had some experience at this.

Economics question: What exactly causes the value of money to go down if more money is in production?

Ok, so I do know that if the amount of money in circulation increases, the value of it goes down, but what exactly makes the value go down?  Why would it go down instead of just stay the same?  In addition to this question, I would like to know how the general public and the government would know about money losing it's value, thus increasing their prices of the goods and services they sell.

When Design Goes Too Far

Here's an image that's been making the rounds today. It's a bed that breaks down into four pieces that can then be interlocked with the floating bookshelves to form some sort of padded wall/bookshelf. It's just a design concept and not meant to be produced (I hope), but even so it's quite a case of a design looking for a problem. A few shelves on the wall will have a lot more storage for books and you can then store a futon or an inflatable mattress underneath. And do you really want your mattress displayed on the wall?

Rougham Kite Festival 2008 - PHOTOS

Single-line, stunt and power kites, plus giant inflatables that need small trucks to anchor them.Artistic displays, stunt shows. Kites to try, kites to buy, kites to make.A high-altitude licence (UK law normally restricts kites to around 60 metres - the festival gets special permission to fly to hundreds of metres) and a real-ale tent.What more could you need? Even the long-term forecast is promising (as opposed to the year before last, when one of the trilobites broke free and landed several villages away).I plan to be there (wearing a Robot tee) do you?LinkEDIT: I took a few photos - I put 84 of them on Flickr
