> they ran some calculations that showed that there should have been some coupling between their object and the water it was passing through, which suggested that there should have been some turning—it was just too small to see. The team has already begun work on a new design for an isotropic helicoid that will demonstrate enough spin to be seen. So it didn't fail? They're gonna try again with a different layout. Would be interesting to see though.
