Easy Wall Fix
When I was about 15 I was doing cartwheels down a corridor in my parents’ house. I fell while inverted and my foot went through the gyprock wall.
Thinking quickly, I took a fragment of the broken wall, scanned it, picked the paint colour out and printed an A4 sheet of the same colour. I then taped this over the hole with Scotch Magic tape (the one that is nearly invisible when you take it down).
My Mum walked past this hole every day for THREE YEARS. When she finally discovered it, and I told her the whole story, she was just impressed by my ingenuity. Story credit: Reddit / jamesinc
