(Step 6) Creating the Obstacles


"One obstacle we made was an elephant.  We tried to make 
the metal marble go threw the elephant's body, but that 
didn't work because the incline was too high. Next we 
tried to make it go through the elephant's trunk. That 
worked out fine. The moving part is the tail on the 
elephant. 

When the metal ball goes threw the legs it gets stuck 
between the two magnets, the tail starts to move. 
The magnets are connected to the tail and one is hot 
glued into the board. The two magnets are - or +. 
When two of the same poles are facing each other 
they try to push apart that makes the tail move." -Amber
