[R-390] Tungsten Disulphide question

[Glenn Scott]

Recently, I required some Tungsten Disulphide powder which arrived in 2 separate plastic storage bags.
I washed and cleaned, very thoroughly, 2) 1 litter diet Pepsi, plastic bottles. They were rinsed thoroughly and dried.

Using a funnel, I dumped the contents of both bags into the 1 litter bottles. They were about 1/3 full each. They have been stored in my climate controlled storage room for the last 2-3 months.

Last week, I went to use some W2S and noticed both bottles were deformed as if the air had been vacuumed out?? The walls were pulled in, although, the vessels seem rigid, at least for now.

Any thoughts on what may have happened to these plastic bottles or hat might be a better storage container??

These were DIET Pepsi bottles, perhaps the bottles are the secret to the DIET since they have lost their width????? Hi hi
