  1. i have someone who has requested magnetic dice from me
  2. how would i make the tiny red dots? just with a pen or something?
  3. ok, i knew that, i was just hoping that it was something you could see with filters only or something.
  4. how does lemon juice and water work? I need the solution or mixture to work on red or blue paper for now. would a UV chemical show up when it is viewed under UV light though (im guessing it would)?
  5. but how do i get it to not "click" to another magnet or metal object?
  6. ok, what i am asking is what can i put inside dice to make them do this, any ideas? the dice would be used for demonstrations, as i already do demonstrations on marked cards and such items.
  7. how does a polarizer work? and any ideas on these materials?
  8. but what i was asking was for a metal of this size that would not stick to another magnet of less power if there was a 1mm space or object in between them, but it would if there was a very powerful magnet. what i am basically looking for is a metal that is not too atracted to magnetic fields?
  9. Is there a substance or solution that can be put on paper or an object that would not be visible no matter how much you added on there. But you would be able to use filters to see the solution or substance. Anyone know anything that would work like this?
  10. i was wondering if there was a type of metal that could be a 1mm cube inside of a 2cm cube and be able to have an visible effect on the big cube when it is on top of an electric magnet. The metal should not be attracted to regular magnets, atleast not enough where a person could feel a regular magnet attract to the 1mm cube inside the 2cm cube. any help or ideas?
