Have been asked a number of times to make a DNA Helix, and think I have 'almost' perfected a quick fast Helix Weave.

3 Balloons, takes about 4 minutes to make a metre long spiral, it's not exactly a Helix as green 160 in the middle zigzags instead of being  a ladder shape.  Any suggestions welcomed...
