Hi cool idea, I like it.
But maybe tell us a little about the fire/explosion danger. Meny batteries are not the safest thing to open up. Is it safe to use all button cell batteries ?

to make the battery dead, wrap the battery with aluminium foil.

You might short circuit by mistake. Good idea. i'd have tried it but it seems a little dangerous... maybe you can do something similar in a safer way...

this is safe. I recommend you to use dead battery and use gloves.

thanks for look my works!

It's button not botton! Just so you know :)

This is not safe. Batteries contain all kinds of heavy metals that are bad to inhale in general, and especially when heated. Do not try this at home, a little surgical mask from the drug store will not protect you.

maybe you right. anyway,thanks for look my works

Even a dead battery contains heavy metals and mercury. Would not take any risk to inhale these fumes.

Can you expand on the "open the battery with cutter and lighter" statement please?

Where do you hold the lighter? Under it?

balsuryana (author)h2OSuz2016-06-10

yes under it. burn the battery to make the plastic inside the battery melt. And use cutter to open it. Thanks for look my works
