You might think of the annual White House Egg Roll as something of a private, limited-invite affair - but in fact it's a major celebration with over 30,000 people sharing the South Lawn with President Obama and his family.

This year's theme "Get Up and Go!" focuses on fitness and health, with healthy eating tips and celebrity chef cooking demos set up around the grounds. There will also be physical activities like basketball, tennis, an obstacle course, dance party and yes - even yoga. Kids in love with Michelle Obama's White House garden will even be able to take home seedlings in their egg cartons to grow their own veggies.

"All of the activities will encourage children to lead healthy and active lives and follow the First Lady’s Let’s Move! initiative, a national campaign to combat childhood obesity," says the official site. 

Like last year, the event is embracing sustainable practices. 83,000 souvenir eggs made from sustainable American hardwood will be given to children at the event, the rest will be sold by the National Parks Foundation. Over 90 recycle bins (and 90 trash bins) will be placed throughout the grounds. While the White House kitchen has a composting system, it apparently does not extend to events of this size.

In addition to the wooden eggs, there will also be 14,500 hard-boiled and dyed eggs used for the egg roll and hunt. As further evidence of "they thought of everything", some eggs will even include a chirping noise to help children who are visually impaired.

While the lottery system to score a ticket has since closed, you can still enjoy the 133rd White House Egg Roll with your laptop. The entire event will be streamed live over on starting next Monday April 25th at 7:30AM.
