Generating ice on foliage: assistance required
Hi all, I'm filming ice in a cold storage container and need to got some footage of white ice/rime/frost forming on various kinds of foliage (mainly moss, leaves and some grass) but am struggling a little.
My attempts so far have largely boiled down to two categories: A) trying to get warm water inside the foliage to frost/freeze, and B) introducing hot water vapour to condense on already-cold foliage.
The container gets down to -30C after it's left a little while and is about 20ft long by 7ft wide. There is air flow but not enough to move hair, so I would estimate less than 0.5m/s. I have been careful not to cycle the door too much and keep the inside as cold as possible.
So far my attempts have been as follows:
1. Introduced largely dry 5-10C foliage to freezer along with a tray of water held above it, left room. Result: foliage froze completely dry.
2. Left foliage to freeze dry, then stood with it breathing and misting it with water. Result: Some ice forming on leaves and grass but not nearly enough.
My next attempts will be:
3. Boiling a pot of water and exposing it next to the foliage, standing with it for the duration.
4. Warming foliage back up to 5-10C, wetting it significantly, and reintroducing to the freezer.
If anyone has any suggestions as to anything I might try, variables I might not have considered, or any ways I might be able to get some nice white ice forming inside this freezer would be hugely appreciated!
