## PF Photo Contest - Watching Grass Grow (9/3-9/9)

Watching Grass Grow

This week, the theme is slooooowwwwwwww. Your photo must convey clearly the idea of something that is moving or changing very slowly. Certainly this concept is subjective and relative. So it is up to the voters in the end to decide if what is being depicted can be considered as being "slow".

Good luck!

Contest Rules:

1. Any digital photo or digitally-scanned photo relevant to the theme will be accepted within the contest period. In case there's a gray area, or you're not sure if the picture is suitable, check with me first.

2. Please resize your digital photo to no more than 800 x 600 or 600 x 800 pixels. You may also crop your picture if you wish. You are also allowed to adjust the brightness and contrast of your picture but these should not dramatically alter the look of the picture. But other than those, any form of picture editing or modification is not allowed. This is a photo contest, not a picture editing/special effect contest. You may add a watermark or your name/nickname to the photo for identification purposes.

3. Upload your photos to any of the photo servers such as imageshack or photobucket. Then post it the relevant contest thread and link your picture using the img command. PM me if you do not know how.

4. Only ONE picture per member per contest. Once a picture is posted, it cannot be changed other than a total withdrawl by that member from that week's photo contest. Exceptions will be made for modification to comply with the rules, such as resizing.

5. At the end of the contest period, I will open a poll and every PF member can vote for the picture they like best.

6. Note that in case we have a large number of entries, I will do the polling in more than one thread. If that's the case, you can vote in each of the polling threads. The photos will be assigned in the polling threads in the order they were submitted.

7. These pictures must be something that you took, not something taken off someone else's photo albums or taken by someone else. I have no way of checking if you did this, so we'll go by the honor system.

8. You can use a picture only once. Once it is used in a contest, it cannot be reused in another contest.

 Admin I have a perfect idea for the picture, unfortunately, flight there and back to Brisbane from here is about $2000, and not being sure I will win I am reluctant to invest this kind of money.

Do you have any historic churches with very old windows, around? My understanding is that the viscosity of the glass can be seen after hundreds of years.

 Recognitions: Science Advisor I used a fluid with a high viscosity, low surface tension, and low velocity to simulate water wetting a glass surface at a high speed (constant capillary number). Photos of the fluid dripping were not as good- those dynamics are controlled instead by the Bond number, so I would have needed to immerse the setup in a neutral buoyancy tank to do the simulation. Perhaps another time....
 I'm sure it took a while for this black widow I found yesterday to grow those 6 egg sacs . . . Attached Thumbnails

Unfortunately, I think this might not conform to the spirit of the contest, since this is several shots.

Please read the rules of the contest. You need to upload it to a photo repository service, and then use the appropriate forum tags. Uploaded file cannot be used.

 Recognitions: Gold Member Some fungi seem to pop up overnight, but this one has been developing for over a month. My neighbor has a very large tree-trunk with an overhanging branch that he hangs his mailbox from. Now it decorated with several clumps of fungi.
