Old Window Hack
Old homes typically mean old windows. Oftentimes, these windows haven't been opened in a while and get stuck. This also happens when windows have been painted and aren't allowed enough time to dry and so when the window is shut, it essentially seals them closed. To get those windows opened back up you just need a chisel and a hammer. The chisel can be placed between the window and the frame and with some light tapping with the hammer, the seal should come loose.
