It's summer, which for some means spare time at the beach, splashing in the waves and...building sandcastles. On today's episode, Emily Kwong asks: Scientifically, what is the best way to make a sandcastle? What's the right mix of water and sand to create grand staircases and towers? Sedimentologist Matthew Bennett shares his research — and personal — insights. Happy building!
