Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles?

The experiment was conducted by Thomas Young and is known as Young’s Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment.

The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach.

Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young’s lecture and the University of Sydney for lending the double slits.

With unprecedented access to land, British Columbia is home to more mountain bike trails per capita than anywhere else in the world. From old growth rain forests to barren grasslands, BC’s diverse landscape allows for every variety of trail to exist in one place. In BC, you can experience the evolution of mountain biking through the trails. From beaten down jumps on a vacant lot to massive back-country booters; from first descents that have never seen the tread of a tire to machine-made masterpieces. These trails connect all mountain bikers, and in BC, trail builders are the force that bring all riders together.

Strength in Numbers is a new community film project from Anthill Films and Red Bull Media House. Presented by Shimano and Trek, Strength in Numbers is being made available for all mountain bikers to experience through free online streaming of individual segments. The vision is to create the potential for every mountain biker in the world to see and share the film. To see the full film uninterrupted, get exclusive extra features and support the filmmakers, order your copy now at http://anthillfilms.com/strengthinnumbers/buy.

We put the infamous “Spider-Man upside down kiss” to the test at USU. Special thanks to all of those who took our “survey.”

Thanks to Utah State University for allowing us to do our video on their campus. Also, thanks to “Bangakang”. They also make funny YouTube prank videos.
Check them here: http://www.youtube.com/user/bangakang

Creighton Baird helped set up the ropes to lower Spider-Man. You may have seen his work in the video “World’s Biggest Rope Swing.” He definitely knows what he’s doing. Check him out here: http://www.facebook.com/creighton.baird?fref=ts

We shot this video using a Canon 5D Mark 3. In order be far enough away so the people didn’t know we were on camera, we used a Canon 70-200mm L series lens. It was very convenient because we could set up the camera far away, but still zoom on people’s faces and capture their reactions.
