This sunday stay up late and watch the annual Perseids Meteor Shower. It’s supposed to be best on the east coast at 2am Monday morning, or in the UK around 10pm Sunday night. Meteor showers are like uber-cool free fireworks, so get ’em while their hot!*
*Note: If a meteor does land near you then don’t touch it. It will be very hot. Actually, if a meteor lands near you then there’s a good chance you’ll be dead from the impact. So remember to duck and cover.
