Micro-aquariums are made with clear silicone , 75mm X 50mm glass slides and a 75mm X 25mm glass slide cut in half for use as a spacer. Place a thin bead of clear silicone on three sides at the edge of one of the 75mm x 50mm slides. Place the 2 half slides (stacked as a spacer “2 slides thick”) on the glass slide that now has a silicone bead being careful not to disturb the silicone. Carefully place the second 75mm X 50mm slide on top of the 75mm X 50mm slide with the silicone bead. Carefully align the slides and clamp with a large paper binder. Clamp on the area containing the half slides so as to not crack the aquarium! Add additional silicone to the rim of the glass “sandwich” until there are no gaps. Let set for 24 hours. Remove paper binder , half slides (spacers) and trim off excess silicone with a razor. Add pond water with a plastic pipette and seal with a snug fitting rubber band. Examine with a hand lens or stereomicroscope. Carolina biological supply sells them for $6.50 each if you want to avoid the labor.
