Bubbles of Steel
Bubbles of Steel by Copernicus Toys:
These bubbles are heroic! How's that? Well, these bubbles can be touched and they won't pop. These are tough bubs. You can make bubbly stacks or even bubble sculptures. Sometimes you find a little bubble weeks later, just sitting there being... not your basic bubble. Physics made adorable. Comes in either green, orange, blue or pink color tube.
