Physics marble track review part one // Homemade Science with Bruce Yeany

track material is easy to work with and cheap. it is called shelf bracket tracks or shelf uprights.

This phenomenon only happens in Hawaii . . . and Cuba & Nigeria & Indonesia & Peru & Sudan & Laos &…

There are apparently no shadows in these images. But they were taken during the brightest part of the day. This episode is brought to you by Squarespace: http://www.squarespace.com/physicsgirl There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at the right time with no clouds! The photos and clips in this video were taken by my mom, Cathy, and friend Noel Liddell in Wailua, Po’ipu and Lawai, HI on July 11th (one day before exact Lahaina noon) and July 12th.
