How To:  Spider Web Balloons

So, the stuff inside the balloon that makes the web is called HI-FLOAT, and it’s a commercial product actually sold for injecting into helium balloons to make them retain their helium longer. It forms a skin on the inside of the balloon and keeps the helium from diffusing out so quickly.

The “web” effect is created by applying the HI-FLOAT and letting it dry at one pressure, and then deflating the balloon, stressing it, and then re-inflating to a higher pressure, causing the film to detach from the walls (which, of course, means it’s not working as a sealant anymore, but whatevs).

I’m pretty sure this trick was developed in-house, by the company that makes it, to sell more HI-FLOAT. Still, it’s pretty cool.

    That’s all well and good and HI-FLOAT is used to make the web but how did they get the spiders in there?!

      Did ya read the linked article from Crafty Crafty?
      You put in the spider at the beginning, with the Hi-Float.

      I’d suggest filling with hot air and CO2 (breath), for longer duration. Hang by the stems, instead of having them float up…
