Upcycled helium tanks

I’ve been holding onto some empty helium tanks, determined that I can recycle or upcycle them, rather than take them somewhere for recycling. My idea was to turn them into outdoor planters. So I got out the angle grinder and fit it with a metal cutting blade, then clamped the tank into my work bench so it wouldn’t wiggle.

Cutting off the top of a helium tank

It wasn’t hard to cut the top off; it took longer to grind the edges so they weren’t vicious sharp. I did what I could with the angle grinder, then used a file. I then flipped the tanks over and drilled drain holes with a stepped drill bit. While my youngest wanted me to leave them pink, I just couldn’t do it. I used black and silver spray paint to obscure the writing.

Painted tanks

When the paint was dry I filled them with dirt and set up some extra drip line. I put onion seeds in one and watermelon seeds in the other. We’ll see if anything grows! At least they look good.
