Up up & Away!!

Check out the picture perfect conditions for a hot air balloon ride.    Dave’s mom Clara is in the higher of the two:  “It took several bookings to finally get the weather to cooperate, but my Mum, Clara, finally got her long dreamed of hot air balloon flight!   It was a 4:30am wake up for my brother and I to drop her off at the meeting point for the 6:00am departure.   The set up is something to see – I was surprised at how huge they are, eventhough I have seen dozens in the air over the years.   We fetched her at about 10:30 and she was over the moon!   It was everything she hoped it would be.”

DID YOU KNOW?   Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air because hot air is lighter than cool air.
A cubic foot of air weighs about 28 grams (an ounce).
If you heat that air by 100 degrees F, it weighs even less, about 7 grams.
So that means each cubic foot of air contained in a hot air balloon can lift about 7 grams.    That’s not much, and this is why hot air balloons are so huge — to lift 1,000 pounds, you need about 65,000 cubic feet of hot air.
