So a couple weeks ago, after Roan was done being "SO angry" with me for dumping his Lego into his toybox, he and I got down to brass tacks (well glass beads rather) and went to work making a gazing ball for Grandma for Christmas (He'd already made her a 'touchy' card and this was to go with it.) Whether it will weather the weather remains to be seen (since it's currently 1 degree with a foot of snow on the ground, we shall not be able to test out its durability until May or so.)
Here's what we used (though the glue may have been the wrong choice, only time will tell. It was fun making it though.)
Hot glue gun and lots of glue sticks
Flat bottom glass beads (multi-coloured would be fun but use what you have)
Sorry I couldn't do a staged shot, but use your imagination will ya? We got snow last night remember!??! And lots of it! Let's gaze into the ball and long for spring. Maybe with lots of eyes looking into it we'll be able to will the snow away. Good luck. Ready? Aim....stare.
