So for my biology assignment on DNA im making a 3D model of a double helix out of foam balls. Ive looked for intstructions on google,etc but cant find anything really detailed or with picturesif anyone has ever made one of these can i just have your advice and so forth or any links

Does it have to be made out of foam balls?

Get two long pieces of sturdy wire and thread the foam balls with a little distance between them. Make a 'ladder' (connect each foam ball on the wires with toothpicks or something) then twist the wires to form a double helix.

Make sure you label each component of your model and correspond it to a part of DNA so you get more marks.

I would say foam balls are fiddly and a bad way to make a model, but whatever works for you.
