This is the elephant I spotted on the web years ago:
I added a 1,5 mm thin ground plate, which lookes like this:
DON´T forget to cut out the little hole on the ground!
I fixed it to the snowball´s base using liquid super glue.
I also used superglue to fix the elephant.
I then used HOT glue to fix the cover to the base.
I therefore put the glue NEXT TO THE GROUND PLATE - not on the snowglobe cover.
You´ll need distilled water - poor in germs - mixed up with a water preperation product. I used an injection nozzle to get into the tiny opening.
To make the snow mix up with the water, I therefore mixed the snow with a little portion of any dish cleaning product ... and finished !!!
Take your time and read about my experiences!
