Household tips on removing bubblegum on fabric, and opening bottles with stuck lids

Dr Abe V Rotor
To remove bubblegum stuck on fabric, freeze it first and peel off.
Don't force to remove freshly  stuck gum on cloth, otherwise it will spread and stick more.  Carefully place stained cloth in the freezer for a few minutes to solidify.  You will be surprised that the gum will peel off easily.  Warm water and a little detergent will take care of the rest of the job. 
 
For bottles that are difficult to open, heat the lid.
This technique ideally applies to glass jars with metal cover.The principle involved is that metal and other materials expand when heated, and contract when it is subjected to cold.  The lid readily expands when heated while the glass jar doesn't expand as much. Heat also melts wax and loosen sticky materials.
