Hi, Thanks for asking about this Education.com science activity!

To confirm the cobweb substance is actually DNA, your student can use a microscope and images of DNA (here are some on Wikipedia: http://en.wikipedia.org/wiki/DNA ).

On the Biotechnology Online website (from the Government of Australia), I also found this similar experiment that encourages students to use multiple different foods to compare and contrast the extracted DNA material:

I hope these resources are helpful to you.
