My youngest, since leaving for college last fall, was home for 4 weeks at Christmas, is now home for a 2 week spring break, and will be here a couple of times over the summer, with the longest stretch being about 6 weeks. He went to a friend's house for Thanksgiving.
What are Sneaker Waves? Sneaker waves are unusually large ocean waves that appear suddenly and without warning. Small children should be watched around the ocean to protect them from the sudden dangers associated with sneaker waves.
Each platform is the size of a pinky nail. The platforms emit sound waves which move upward until they reach surface lying above, where they bounce back. When the downward-moving reflected waves overlap with the upward-moving source waves, the two âcancel outâ in the middle, at so-called node points. Objects placed there remain stuck in place because of the pressure of sound waves coming from both directions (see picture below). Dimos Poulikakos.
