I did not know foil could help with this until someone showed me the old laundry trick.

A smooth ball of aluminum foil can sometimes help reduce static in a dryer load. It is not magic, but it can help separate fabrics and cut down on cling.
How to Try It
- Tear off a clean sheet of aluminum foil.
- Roll it into a smooth ball with no sharp edges.
- Put it in the dryer with towels or sturdy everyday clothes.
Do not use torn foil with sharp points, and skip this trick for delicate fabrics. If your dryer manual says not to use anything like this, follow the manual.
Did your family use foil, dryer sheets, or nothing at all?
