Visual representation of cell membranes

[O/A Level Biology / Chemistry] A bubble with a hole in it may seem rather odd, but that is entirely possible by using some clever items you can find around your house. And the result closely imitates the way cell membranes work, by allowing selective nutrients to enter in and out of the cell.

For students looking to enter the biochemistry firm (or simply studying A-Level Biology / Chemistry in general), this is a must-watch to grasp a concise understanding of the nature of cell membranes and phospholipid bilayers.
