Building a Rocket Ship!

It all started with a cardboard tube telescope and a crescent moon and Jupiter.  Usually by 7pm we are in full bedtime routine mode.  But after brushing his teeth Cannon wanted to spend a few minutes outside this evening in the dark.  A few minutes wasn't enough for him, so I asked if he wanted to spend five more minutes outside or read his usual three books before bed.  He chose to stay outside and decided that we needed to go to the moon tonight.  He was very serious.  I sensed the importance and decided to run with it.  He spent almost two hours planning this trip, gathering the necessary provisions, and building his rocket ship.  I was just a listening ear and then later invited to be a passenger.  He started with his gear: a suit, socks, boots, helmet, mask, and gloves.  He thought of dry foods, like saltines, to pack.  Of course we needed pillows and blankets, things to do, and a map.  Initially he wanted me to drive him to the nearest rocket ship, but since there weren't any available on such short notice he decided to build one with an extra cardboard box we had lying around.  We all (Cannon, myself and Blue) got in and waited for the wind to take us.  When that didn't work he thought that we need to get air somehow.  So he got out the bike pump.  When that didn't work he realized that his rocket ship needed wings to fly.  When that didn't work he used the packaging air bags to tie onto the ship.  He was very disappointed when that didn't work either!  He then thought if only we had some balloons, that would surely work.  He said, "Mom, I used all the perfect things.  Why isn't my ship flying?"  He asked, "Why can't boxes float in the air?"  He hasn't given up on his idea yet and the rocket ship waits patiently in the living room until tomorrow.
