8. Cornflour Helps Untangle Knots

Cornflour (or Cornstarch as it is also known) has many interesting uses other than just an ingredient for thickening sauces or gravies. Knots in a string or shoelaces can be difficult to undo, but the solution is easy. Just sprinkle the knot with a little cornstarch and you'll be able to easily work the segments apart.

7. Make Cottage Cheese And Sour Cream Last Longer

Foods like cottage cheese and sour cream will last twice as long if you turn the container upside down when you store them in your fridge. Doing this forms a vacuum and prevents bacteria, which extends the shelf-life of these items.

Buff the disk lightly going from the center to the outer edge in a straight line. Again, do not rub in a circular pattern. Wipe off any excess. Hopefully the disc will be (almost) good as new.
