Magnetic-Shape Memory Polymer(MSMP)
00:19
Able to change shape respect to the direction of the magnetic field
00:38
Now! Lets use the property of our material to create an intelligent light barrier
00:45
What do we want it to do?
00:49
1. It can block light passes through it when it is flat (State 1) 2. It can allow light passes through it when it is extended (State 2)
01:01
Materials!!
01:04
Paper Towel ----MSMP • Small Light Sources(iPhone or iPad) • Scotch Tape • Strings ----- Magnetic field • Scissors • Better to have: Shoe Box
01:23
The box is used for better observation
01:27
Cut the top and one side of the box
01:32
Poke several holes at the bottom of the box
01:36
Design your barrier
01:58
Use tape to stick the paper on the table and the strings on the paper. Strings are able to go through the holes on the box
