With the thin sharp knife or scissors , cut the stem lengthwise in half , going upwards , but do not cut it off the stem .
Now using the same knife cut each stem half in half lengthwise up the stem so to make 4 even dangley bits of stem hanging from the rose .
Place one of each food colouring per shot glass till each of the shot glasses are pretty full .
Next place one piece of rose cut stem per food coloured shot glass , making sure the stems are emerged into the food colouring in the shot glasses . ( you may need to prop your rose up with something to balance it , i used my vase lol ) .
Now set aside and leave it all sit for a few hours so that the food colouring can travel up the stem so to make the petals colourful .
Once roses have changed colour , rinse the stem ends that were submerged in the food colouring and but off the 4 dangley bits to even up the stem .
Place coloured flowers into a clean vase with clean water for people to see . Have fun . :-) .
