Hi cool idea, I like it. <br>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. <br>
<p>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...</p>
this is safe. I recommend you to use dead battery and use gloves. <br><br><br><br><br>thanks for look my works!
<p>hello? tsa? xD</p>
<p>It's button not botton! Just so you know :)</p>
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<br>
<p>Even a dead battery contains heavy metals and mercury. Would not take any risk to inhale these fumes.</p>
use masker to keep you better and use gloves to make it safety. Thanks for look my works
<p>Can you expand on the &quot;open the battery with cutter and lighter&quot; statement please?</p><p>Where do you hold the lighter? Under it?</p>
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
<p>nice</p>
Thank you!<br>
