Cornell’s fashion design students were challenged to create an innovative evening ensemble, but the hitch to the task is that they had to do it with no thread and no glue.

So they turned to a process known as ultrasonic joining using the SeamMaster High Profile which has been used for body bags and bullet proof vests but not something as fine as cocktail and eveningwear to develop floral appliqu?s and spaghetti straps.

If you’re comfortable with basic physics you may have already figured out how this process works: the hi-freq waves are concentrated in a tiny single spot on the fabric which creates a rapid build up of heat. Since the fabircs used are mostly synthetic the heat allows the fabric to be fused together.

Cornell Chronicle has the details.

If you have a large amount of spare or extra business cards, and plenty of time to spare, then try this on for size.  Building a Menger’s Sponge is quite an undertaking, depending on the depth you wish to create.  Dr. Jeannine Mosely took it upon herself to create a level 3 Sponge, using over 66,000 business cards gathered from friends and family, and hundreds of hours of extra time.

This looks pretty fascinating to me!  The fact that it’s self-supporting is amazing in itself, not to mentions that it just looks cool
