What are some smart and creative ways to building a DNA model without using any type of food?

My physics teacher is requiring my class and I to build a DNA model that can stand upright by itself. He will try to prove that it is strong enough to stand on its own. Such as, by trying to knock it down with the force of wind, and gently shaking the table the DNA model will stand on. Basically, my DNA model must be made of strong and sturdy materials in order for it to cover the expected requirements.

You're help is very much appreciated! Thank you so much!What are some smart and creative ways to building a DNA model without using any type of food?
You could try using tooth picks(they sell a variety of colors) and maybe pop sickle sticks(found at craft stores). Regardless of the material, you could buy some velcro(at Target or Wal-Mart), cut it to the desired size, and use it to create your hydrogen bonds.What are some smart and creative ways to building a DNA model without using any type of food?
i was gonna say toothpicks as well, you could possible thread beads onto them as the bases and use thread to represent the bonds??
