8. Invisible Glass
Materials Needed: superglue, PVC pipe, a piece of paneling, 2-3 tubes of glycerin of 100ml, smooth and transparent drinking glass and an empty transparent bottle clean and try with a screw on top.
In order to make the invisible glass experiment, you need to fill the bottle with glycerin and screw the lid. After this, fill ⅓ of the glass with glycerin and place the bottle in the glass until one part of the bottle is submerged. The following steps are optional. You can superglue the PVC pipe and put it in a piece of paneling as a glass holder which will keep the glycerin from spilling over.
