We just hosted the RE/MAX Hot Air Balloon at Bill Burden Elementary this morning...it was awesome!!  We sponsored along with RE/MAX of Texas to have the hot air balloon come out to teach the kids about how hot air rises.  They were taught a little about the history of hot air balloons, but mainly about how they operate and the science behind it.  THEN, there was of course a demonstration which they LOVED!!!  The school was great, the pilot was too, and the kids had a really good time.
