This is Ben Gonyo from Expert Village and
we're building a kaleidoscope. In this tutorial, we are going to assemble our lens. So, it's
pretty easy, all you do is take your hot glue gun and put a little bit of glue
around the edge of the lens piece. As little bit of glue as you can use is fine; that way
it will stay cleaner. And then you just place your transparency on there and you have half
of your lens. If there is a little bit of extra glue you can clean it off, and if you
have a little bit of overhang with the transparency. You can take the exacto blade once it's cooled
off and trim that back. So that it is flush. We are going to put a little holder in the
lense, in the middle. You don't have to do this, but it holds the pieces in place. It
is just a triangle piece of cardboard and you then put your beads in there. You can
use your cut up transparency and color it with some markers and let that dry. Cut this
into bits (old film negatives will also work). You put the bits in there and they bounce
the light around into different patterns. We are going to seal it up just like we did
with the other half. We are just going to put some glue around it, and seal it up.
