If you had your birthday party on the moon, what would it be like? Blast off to an extraterrestrial celebration and find out! This cool picture book combines fun and facts to help kids learn all about outer space. Have your birthday party on the moon and everyone will come! After all, who wouldn't want to ride in a rocket and celebrate for a day that lasts as long as a month on Earth? Then, young partygoers could romp in a low-gravity playground, watch candles and balloons behave weirdly in the Moon's atmosphere, and see why the moon angels they make in the thick carpet of lunar dust will last for thousands of years. With each discovery, kids learn the science behind the surprise, explained in terms they'll understand. Complete with sidebars and a glossary, this entertaining adventure is perfect for sharing at home and at school.
