Magnets Hinge and Weld - none great (add friction to hinge?)

(I later realized the possibly obvious workaround - add a “end of string knot” layer about the rest of the balloon. Make the balloon and string a nested independent layer and put dangle on that (no collision - dangle and collision don’t work together). Put collide on the “knot” layer (I used a circle). So the string attaches to the knot, the knot attaches to the hand. The knot spins around a lot, but using hinge to attach the balloon to the knot means the balloon dangles nicely. I then made the knot invisible so you cannot actually see it. That workaround works pretty well - but I still think adding friction to hinge to slow down the spinning would be helpful.)
