Our noses are amazing! Did you know we are nanosensors – instruments that can detect things billionths of a meter in size? That is basically what our sense of smell is able to do. And even though our noses aren’t as sensitive as some animals, they are still pretty sensitive.

Try out our Smelly Balloons experiment highlighted in this O Wow Moment episode from the Children’s Museum of Houston. Just add a little flavor extract to a latex balloon and you can still smell it! Create several and make a game to see how many people can guess correctly! But, just be careful about with whom you play the game…

Nanoscale science, the study of the behavior of particles that are billionths of a meter in length (think around the size of small viruses) and their potential applications is constantly in the news! But how to make sense of it all? Well the Children’s Museum of Houston is fortunate to be a part of the Nanoscale Informal Science Education Network (NISE Net) which has lots of information about nanoscale science and nanotechnology, including some basic introductory information as well as fun activities through its website at www.whatisnano.org. Many thanks to NISE Net who, thanks to a generous grant from the National Science Foundation, funded this O Wow Moment Episode.
