Random reddit comment about superglue and baking soda changed my cracked phone stand fix

I was trying to fix a broken plastic phone stand that snapped at the hinge, and some dude online mentioned mixing superglue with baking soda makes a rock hard filler. Gave it a shot on a 25 cent thrift store find earlier this week and that joint is now stronger than the original plastic around it. Has anyone else tried weird combo hacks like this that actually held up way longer than expected?

oh i saw a video on tiktok where someone used the same trick to fix a broken gaming controller trigger. they mixed the baking soda into the superglue til it turned into like a paste then applied it to the crack. apparently it bonds so hard it basically becomes like ceramic when it dries. i tried it on a cracked plastic garden tool handle and its been holding up for months now through rain and dirt. way better than normal superglue which always just snaps off again.

See, I gotta respectfully disagree with this one. The baking soda trick works for filling gaps but it makes the glue way MORE brittle, not less. Once that mix hardens it turns into basically a hard crust that'll crack under any flex or impact. Real superglue actually needs a little bit of give to stay bonded to plastic, especially on something like a garden tool handle that bends and twists. I've had that exact same fix fail on me twice before I gave up on it. A two-part epoxy or even just plain old superglue with a primer is way more reliable for anything that actually takes stress.
