Magic Box??

[futtech]

I recently downloaded a flipchart that uses a magic box, and I cannot figure out how it works. You move a bow with text through the box and a new set of text appears in place of the other. Does anyone know how to make such a box?
Thanks

Can you post the flipchart or the link here so that we can see a little bit better what you are talking about. I think I know what you mean, but it would help to be able to see it...

This works by having two versions - the one you can see which is on the top layer and a second underneath on th bottom layer. These are grouped together so that they move as one item.
Inside the 'magic box' is an area created using the eraser tool - a big 'rubbing out'.
When the writing is moved into the box, the eraser area 'rubs out' everything on the top layer - just leaving you with the answer (everything on the lower layer).
Hope this makes sense - you might want to search for 'magic eraser' on the forum fro more info9rmation and uses of this technique.

A really easy way is to have 2 colours of text - one the same as the background so you can't see it in that sector of the page.
When you move the object across into another sector with a different block of colour, the answer is revealed because it stands out against the background..
