As a child, I loved science experiments. If you read this website regularly, however, you know that my efforts were not always successful 🙂
Source materials were limited to an occasional viewing of Mr. Wizard, books I could cull from the local library, and whatever primitive experiments I could cook up from my own mind. A chemistry set, received as a Christmas gift, was a rare and highly coveted possession.
Hence, at the time, the appeal of DIY (do-it-yourself) was huge, long before the phrase was co-opted and marketed. To take household items and create novel effects is magic, for a child as well as an adult. Many counter-intuitive results can be had from ordinary ingredients. Let a child do it himself/herself, and you have a formula for wonder and awe.
Unlike the San Gennaro festival, e.g., many of New York City’s most interesting events do not have a centralized location. You could be in a neighborhood where numerous concurrent events are going on and not even be aware that they are part of a major festival. See Math Midway, part of the World Science Festival, here.
This scenario replayed itself on Sunday afternoon, when I discovered that the annual 3-day Conflux festival was essentially over. Produced by Glowlab in New York since 2003, “Conflux is an art and technology festival for the creative exploration of urban public space.”
So I was quite pleased to run into a DNA Extraction Party while strolling through the Tompkins Square Park farmer’s market. I was not aware that DNA could be extracted from fruit (or other living things) using common household ingredients – meat tenderizer, dish washing detergent, salt, alcohol, and a coffee filter. Note the clump of DNA between the fork and chopstick in the photo. This experimental display was produced by DIYBio NYC.
It is likely that a very young child would not fully appreciate the outcome. In the experiments I did as a child, results were immediately obvious and did not require an understanding of deoxyribonucleic acid, genetic instructions, and a double helix. However, this is 2009, and the bar has been raised. But the spirit of Mr. Wizard lives on 🙂
Note: Mr. Wizard (Donald Jeffrey Herbert, July 10, 1917 – June 12, 2007), hosted the Watch Mr. Wizard TV program, which ran on NBC from 1951 to 1965. In 1983, Herbert created Mr. Wizard’s World, a faster-paced show on the cable channel Nickelodeon, running until 1990 and in reruns until 2000.

Very cool! We used to make these science-for-kids experiments at our department too! They loved the eating ice-cream-comets made with liquid nitrogen… 🙂 and we loved seeing those bright eyes and happy faces enjoying the science we were presenting. I miss that! Thanks for reminding me how great the science 'fairs' are
Experiments are fun! And we as a family experiment the ones posted in the "Wired" magazine… they are so much fun.
