I had cleaned the fry daddy and was re filling it with vegetable oil.
The oil was thick and hard to scoop. I decided to put it in the
microwave for about 10 seconds to melt the outside layer so I could
scoop out the oil better. The container was plastic and the bottom
was plastic, but I knew I should not leave it in the microwave for
long. I had already removed the plastic lid.

About 10 seconds after I put it in the microwave it sounded like
Frankenstein's lab. Buzzzzzztttttt What I had not noticed was that
the seal was made of aluminum. I had cut the seal off at an earlier
date and only a small amount of aluminium was around the lid.

I guess there was no harm, no foul, but what they say about not
putting aluminum in the microwave is true.
