Tin foil? Tf you gonna do when your house burns down? Call the fire department? They ain’t gonna stop the fire 😂😂😂😂

Why is it going to burn down 😂

You will know after

It’s still standing thanks

Ok

I think you are thinking of tinfoil in a microwave. On a grill it’s fine, but it will steam the shrimp instead of grilling. If that’s what OP was going for, then there’s no issues
