DNA discovery, structure and replication

To represent DNA, Dr. Lowe gave us Twizzlers, Jelly beans, and toothpicks to make a strip of DNA. My partner and I put 2 different colors of jelly beans on a toothpick and 2 different colors on another toothpick. We did this with 7 toothpicks, but keeping the 2 colors with each other, but changing the order(picture below).
We then took the toothpicks and broke them in half, now my partner and I having half of the DNA strip. Using the same color pattern we replicated the DNA, finishing it off by adding another Twizzler to the end of the toothpicks. 
This was a great way to represent DNA as a hands on project. For me, it is hard to visualize tiny things like cells or DNA, but using things that I can see and touch is very helpful. I would definitely use this in my classroom one day.
