0:15:04 > 0:15:06Hi, everyone, and welcome to the Science Fiction lab.
0:15:06 > 0:15:10I tell you what - we're really going to take the bull by the horns today.
0:15:10 > 0:15:12BUD E, what's today's question, please?
0:15:12 > 0:15:13How are you, love?
0:15:13 > 0:15:17Just doing a spot of spring cleaning on me old hard drive there.
0:15:17 > 0:15:19Today's question comes from Jean in Skibbereen.
0:15:22 > 0:15:24Ole, ole!
0:15:24 > 0:15:26White light is made up of a spectrum of colours.
0:15:26 > 0:15:29These are red, orange...
0:15:29 > 0:15:31Er, red, orange...yellow...
0:15:31 > 0:15:33Er, red, orange, yellow...
0:15:33 > 0:15:36Red, orange, yellow, green, blue, indigo and violet.
0:15:36 > 0:15:37They're the ones. Bang on!
0:15:37 > 0:15:41Now, unlike humans, bulls are unable to see all of these colours.
0:15:41 > 0:15:44For example, they can't tell blue from orange or red from green.
0:15:44 > 0:15:46HORN
0:15:46 > 0:15:47So if I had a red flag in bullring,
0:15:47 > 0:15:50dressed in a big red coat, with my face painted all red,
0:15:50 > 0:15:52it wouldn't matter a bit to the bull?
0:15:52 > 0:15:54Well, not exactly.
0:15:54 > 0:15:56In a bullring, the noise of the crowd
0:15:56 > 0:15:59and any sudden movements will frighten the poor animal,
0:15:59 > 0:16:02and this might make him angry and cause him to charge.
0:16:08 > 0:16:09Argh!
0:16:10 > 0:16:14So, Jean, even though you should be very careful around bulls,
0:16:14 > 0:16:17you now know they don't have an issue with the colour red.
0:16:17 > 0:16:20That's just a load of old science fiction.
0:16:23 > 0:16:26Do you like my flag, Dr Knowles? I stitched it myself last night.
0:16:26 > 0:16:28It's a nice shade of red, isn't it?
0:16:28 > 0:16:30SHE GROANS
