I have a plastic water bottle that I dropped. It now has a dent in the base, and is somewhat unsteady when standing up. How can I repair this dent without causing cracks in the plastic that will cause it to leak?
Fill it with sand, salt, sugar, or some other granulated material. Use a dowel to pack it down. With enough pressure in the correct area, the dent will pop out.
I found that just blowing compressed air into the bottle will expand the area you want to its original shape.
Put the empty bottle with lid on in the freezer. After a few hours, take the bottle out and put it in the hot sun. The pressure of the expanding air hopefully will pop the dent out.
If your saying the bottle is extruding on the bottom (or pushed out) Simply get hot steam in the bottle and use an object to push the base inward.
Fill it with water and swing it around with the cap off (possibly on a rope). Centrifugal force will push the bottom outward and fix the dent.
Simply push the dent with something hard.
If its made of metal, fill it with water and put it in the freezer. if the bottom expands out when you do this, tap it with a hammer.
Cold water with ice inside.. pour boiling hot water on the dent outside
