Happy Saturday! Dan's here to tell you everything that's going on in the world of science. Carlos Frenk is here to tell you all about the wonderful science activities going on next week for the Royal Society Summer Science Exhibition, including a chance to conduct your own experiments! Carlos is an astronomer, so Dan also found out some of the biggest unanswered questions of the universe that he'd like to answer... In science news, white spots might help monarch butterflies migrate and an app can care for elephants. You've been sending in your questions and this week they're on why salt makes us thirsty and why eye colours are different, and the WEIRDEST WORM on the PLANET makes a gruesome appearance in Dangerous Dan!  Join Fun Kids Podcasts+: https://funkidslive.com/plus See omnystudio.com/listener for privacy information.
