Things We Saw Today: This Sonic Tractor Beam Can Levitate Objects

• I had to see a performance of 1776 for a history class in school, but kids these days? They get to see Hamilton, Lin-Manuel Miranda’s hip-hop musical with a diverse cast — look, just listen to the Hamilton soundtrack, all right? Don’t wait another minute. (via Deadline)
• Artist Keren Rosen has illustrated popular idioms in adorable cartoon form, from “Hold Your Horses” to “Window Shopping” to “From the Bottom of Your Heart.” (via Laughing Squid)
