- I am not a materials scientist, but I regularly read this group with interest.
- I just found an interesting material that solved an awkward problem for me.
- To support a large Christmas tree, I built a wood stand that included a plastic
- water pot that was intended to be nailed between tree butt and wooden supports.
- It was supposed to be self-sealing, but mine wasn't quite. Drip, drip, drip.
-
- What to do? Large heavy tree is already erected on a stand that can't be removed
- non-destructively. No direct access to either side of the leak. It's not real
- easy to even drain the pot. Drip, drip, drip.
-
- Spoke with a garden shop in Beaverton that sets up trees for many local
- merchants. This guy is to Christmas tree stands as Col. Sanders is to chicken.
- Without hesitation, he recommended a product called Water Grabber, a little
- packet of granules. The package says "A water retention additive for
- plants", "Stores water", and "contains polyacrylamide".
-
- I added a packet to the water in the pan, mixed another packet with about
- 1 pt of water, and poured that in. It soon changed the liquid to a wet
- gel.
-
- Result: in 30 minutes, the leak stopped. It's been dry ever since,
- (over a week) even when there is free liquid in the pan.
-
- I'm pleased with this solution (pun inadvertent). Hope someone else can
- benefit from this experience.
-
- I would not recommend it for leaking aquariums.
