0:20:04 > 0:20:06Welcome to Science Fiction,
0:20:06 > 0:20:08where we take the stuff you thought you knew about science...
0:20:08 > 0:20:11..and see if we can sow in a few seeds of doubt.
0:20:11 > 0:20:14BUD E, my old pal, can we have today's question, please?
0:20:14 > 0:20:16Not a bother.
0:20:16 > 0:20:19Today's question comes from Simon in Ennistymon.
0:20:19 > 0:20:21Will singing to my plants help them grow?
0:20:21 > 0:20:23HE COUGHS
0:20:23 > 0:20:27# Let's see what the science says, Simon. #
0:20:27 > 0:20:29When we breathe, we take in oxygen from the air,
0:20:29 > 0:20:32which helps make energy to fuel our body.
0:20:32 > 0:20:35This process also creates carbon dioxide and water,
0:20:35 > 0:20:37which we then release into the air when we breathe out.
0:20:37 > 0:20:41Now, luckily for us, plants love carbon dioxide.
0:20:41 > 0:20:43# Don't they, Dr Knowles? #
0:20:43 > 0:20:45They sure do, Professor.
0:20:45 > 0:20:47Along with water and energy from the sun,
0:20:47 > 0:20:49plants use carbon dioxide to grow,
0:20:49 > 0:20:53while at the same time producing... You guessed it.
0:20:53 > 0:20:54Little fluffy bunnies?
0:20:54 > 0:20:56No, Professor! Oxygen.
0:20:56 > 0:20:59I'm only messing with you. I knew that.
0:20:59 > 0:21:01This process is known as
0:21:01 > 0:21:03photopront...
0:21:03 > 0:21:04Prontophsyn...
0:21:04 > 0:21:05Syntoph...
0:21:05 > 0:21:08- Photosynthesis?- That's the one.
0:21:08 > 0:21:10# Photosynthesis, photosynthesis
0:21:10 > 0:21:11# Photosyn... #
0:21:11 > 0:21:12Ow!
0:21:12 > 0:21:15So, Simon, singing, or even speaking, to a plant
0:21:15 > 0:21:19will help it grow, as you are feeding it carbon dioxide and water.
0:21:19 > 0:21:21But, like, it's not because they think
0:21:21 > 0:21:23you've a lovely voice or anything.
0:21:23 > 0:21:26You're not that good. So that's just a load of old science fic...
