PSA Microgravity Challenge
Preliminary Designs
Bullyard State School
Mr. Brennan's 6/7th Grade
By Ryan
This design of the year 6/7 class of Bullyard state
school that they think is workable. There is a fan on the bottom of a
curved shape piece of pipe. The pipe is there so the wind does not escape
out of the sides. The ball is on top of the pipe so when the when the
air reaches the top the ball will use bournellis principal which is floating
without physically touching it. The wind will keep going up the pipe to
make bournellis principal.
Response from Expert Dan Andrews:
This looks like a great way to have the ball
float in air, but what about when the ball (PSA) tries to move?
If it tried to move down (into the flow of
the air), could it?
What about if it tried to move sideways, and
therefore leave the flow of the air? Wouldn't it fall on the floor?
Would something like an air-hockey table work
better? If so, how could you make a ball move up and down on an air-hockey
table?
