Uranus and Neptune are made primarily of hydrogen compounds, with smaller traces of hydrogen, helium, metal and rock. The most common hydrogen compounds are methane (CH4), ammonia (NH3), and water (H2O). The farther away a planet is from the Sun, the cooler its atmosphere will be.
Musical.ly is a popular app for creating 15-second music videos. How it works is kids select snippets of popular songs and record themselves singing, lip-syncing or dancing. Some kids skip the music and perform 15-second comedy skits.
But what makes musical.ly special is the way that youâre able to combine these features to create something new. Fifteen-year-old Baby Ariel is the top muser on the platform, and has used her musical.ly audience to gain a massive following on YouTube and Instagram.
