About this Product
this is another tool for studying and understanding seifert surfaces. you simply dunk it in a soap solution and pull it out, the head featuring the two links will gather bubble film and with some slight pruning of excessive films, you can cause the nunnle to take on the shape of the two link seifert surface. and, it can be used over and over again to understand the relationship between the surface and its defining edge.
