Hot Air Balloon

Before Take Off

The Proposal
So as we all know by now Mr.Chung likes to present us with seemingly impossible tasks.  After finishing with out egg landers we have moved onto creating hot air balloons with the given materials: a plastic bag, 25 straws (from the egg lander), unlimited tape and 10 candles.  The requirements were to fly 5 cm above ground for 20 seconds.

The Design
Our design was to make a pentagon base with 2 candles per straw.  We also cut the bag in half so that it would be easier to fill with hot air.

The Results
As our group was excited for take off I began lighting the candles one by one.  Tanya and I are faithfully holding the corners of the bag slowly waiting for the bag to fill with enough hot air until it could fly.  However as Mr.Chung grew impatient he decided he would help and held the bag by the wrong corner and burnt a hole into our bag.  Thus ends the life of our hot air balloon.
