Household tips: Aluminum foil in freezers and cutlery disposal
A viral household tip suggests placing crumpled aluminum foil balls in freezers to act as thermal mass. Because freezers operate more efficiently when filled with solid mass rather than air, the aluminum balls can help stabilize temperatures and buffer heat when the door is opened. While aluminum conducts temperature well, there is no scientific evidence that this trick measurably improves food preservation, though experts generally recommend keeping freezers full to maintain efficiency.
Regarding the disposal of old cutlery in Germany, stainless steel items should typically be taken to recycling centers as scrap metal. While some municipalities allow individual pieces to be placed in residual waste, they generally do not belong in the 'Yellow Sack' (Gelber Sack), which is reserved for packaging. Silver cutlery with specific hallmarks (such as 800, 835, or 925) holds value and can be sold to jewelers or antique dealers, whereas silver-plated items may be donated or recycled as scrap metal.
