I myself have found holes in foil covering acidic foods like a pot of sauce. I always assumed it was acid attack. I also switched to using the pot's lid or saran if I have no lid.

I'd like to know how much electrical energy a pan of lasagna contains and whether a discharged lasagna cell has a different flavor. Now I just need to invent a baking cell, a pan with insulated pockets so I keep my laptop and belly full ;-)

This is one of those joyful concepts you learn about as a homeowner, especially on older homes.

If you have plumbing that's done in different metal materials (copper, steel, lead, etc.) and any of your pipes touch, you have to perform regular maintenance and apply a dielectric grease (another one of those single-use materials that you have to buy and store away) or your pipes could corrode and cause a ton of damage.

Interesting phenomenon I hadn't heard of before today. It looks like someone else thought to cross-post this from Reddit!

I would like to announce I am now working on a business plan to bring lasagna powered EVs to the masses.

I recall way back in the day when Stephen Fry used to host QI, they did a bit about a lasagne battery. Sean Lock was on the panel if i remember and spun it out into a ipod-style "lasagne-pod"

The same can happen in those double walled can coolers, depending on the alloys. I put a frosty can inside one and forgot to take it out. The next day, there was a ring of corrosion at the bottom of the can cooler.

Strange, this once happened to me with a tres leches cake that I made in a metal pan and covered with foil. The next morning the foil had tiny holes and the cake was covered in metal filings!

Surprised and delighted to see a Meathead post on hackernews.
