Timelapse

A cut Chrysanthemum stem was placed in a vase of red-coloured food dye for five hours. During this time, the food-dye was transported up the stem by the xylem vessels into the leaves and petals.

Hibiscus plant flowering over a period of 3 days.

Time-lapse demonstration of the separation of felt-tip pen inks by paper chromatography over a three hour period. Samples top to bottom: light green, dark green, brown, black, orange, light brown, red

Time-lapse of separation of food dyes by paper chromatography over three hours. Samples from top: Red = Carmoisine(E122, C.I.14720) and Ponceau4R (E124, C.I.16255) Green = Quinoline Yellow(E104, C.I.47005) and Green S (E142, C.I.44090), Blue = Carmoisine and Brilliant Blue (E133, C.I.42090), Yellow = Quinoline Yellow and Allura Red (E129, C.I.16035), Black = Green S, Carmoisine and Quinoline Yellow.

After a year, 6 assassin snails (Clea helena) have increased to hundreds. When an algal wafer is dropped into the tank they emerge from the gravel in vast numbers. There are also Neon tetras (Paracheirodon innesi) and the normally reclusive Otos (Otocinclus sp). The snails disappear when the food has gone. (108 minutes condensed into 27 seconds).

Short timelapse sequence of leaves expanding.

An impromptu timelapse sequence of a bouquet of flowers opening over a three day period. Lighting was not controlled, hence the flickering but an interesting insight into unseen activity in the living room.
