| Objective |
To make a film (like a soap film) that
can support the most weight by surface tension alone. |
| Participants |
Teams of up to four. |
| Materials |
- Inner ring (provided by Science Olympics organizers) made of
#32 nichrome wire, which is 4.3 cm in diameter and 0.05 grams
in mass.
- An outer ring, which is devised and constructed by each team,
using any materials desired. The ring can be any shape, provided
it is no more than 10 cm in diameter and 80 cm in area.
- The solution to support the weight, which is designed by each
team and may be of any liquid substance (e.g.. soap, detergent,
etc ...) No form of glue may be used.
- The torsion balance will be provided by organizers.
|
| Rules |
1. Two concentric rings are
dipped in a solution. The outer ring is fixed (to a table) and the
inner ring is allowed to move freely. |
| Judging |
The weights are to be added to the inner
ring, and the team whose apparatus supports the most weight, without
breaking the film surface, wins.
