Drilling hole in Exo Terra

[Mentat]

.

Hi Gail ! Above is a nice and easy tutorial. Go slooooooooow and do not press down on the drill; let the drill weight do the job. Do place a towel inside the enclosure to catch the falling drilled out glass piece. I know of a case where the glass piece fell into the facing glass pane and cracked it . This next video is a little high tech since it uses a guide; but the narrator (with sleep inducing monotone voice ) includes a few good tips. Good luck !
