PET, as most plastics, shrinks when heated. In this tutorial we show you how to take advantage of this property to shrink wrap objects with PET bottles.
This is actually very useful. Not necessarily good for foods as pet bottles release chemicals when heated. But big heat-shrink is always welcome, especially if it is free! Good video as always :)
If anybodies interested. LDPE Low Density Poly Ethylene bags bottles or sheet will shrink at low heat & have softer stretcher feel. thin HDPE High Density Poly Ethylene will need slightly more heat & have more shrink & be strongest. Peace Out!
Did you know that you can expose the bottles to a radioactivity source to make them shrink even more? That's a treatment they do to those shrinking plastics we are using to isolate wires.
Great way to wrap small 18650 battery packs. no need to buy the commercial shrinkwrap really.. and this should act as a stronger & more resilient shell for them as well
As soon as I saw the large electrolytic capacitors I thought that has to be very dangerous if you get polarity wrong the safety vales are covered by the shrink wrap and wont function making the whole thing explode instead of just shooting steam out of the top. Otherwise great life hack.
Great ideas in these videos. Since you obviously know what you are doing do you think the block of capacitors could be used to replace a lead acid batter in a scooter?
Yes i have. This video is probably a hoax. Ultracaps or super caps are rediculously expensive and aren't cost effective. I can imagine using large value 200 volt electrolytic capacitors will do the job just fine and probably last alot longer.
If the transformer gets hot enough it will melt it and eventually could catch it on fire if the transformer can get hot enough to boil water minimum. Safe to say if it gets that hot you will have far worse things to think about.

This is a superb idea, if only to avoid the sharp corners of the transformer. Thank you for sharing your idea.
Kudos. Very cool idea. I can already think of a couple places to use this.
life skill that won't be forgotten
wow its perfect for capacitor banks! thanks for sharing this
thank you very much for thia gem. im going to use this for a long time
It's odd, but I was thinking about this the other day and then completely forgot I'd been thinking about it. Thanks.
Fantastic Idea for Electronics works.

very good information to use a lot of space
Excellent video.
Always great info! Thanks Ludic :)
this is a great idea for reusing those bottles
Very cool, thanks
very very good idea
Das ist ja sowas von originell!! What a great idea!!
So that's how they make the apples so shiny ;D
Awesome tip, thanks for sharing that!
This is genius.
good and great idea

You are genius.
Good idea thanks.
bella idea bravo
Amazing idea
I'm going to try to make a 9v battery holder that way. :)
Brilliant.
Tks, hot stuff.
Love this!
Thank you
This is an actual "life hack"
i missed the video where you built that cap bank ,would you please re post it here.thanks for sharing always great videos.
didn´t make a vid on the cap bank
i feel better now thanks

you could put a spacer that doesn't cover the breaking points between the caps and the plastic
I like it
Great ideas in these videos. Since you obviously know what you are doing do you think the block of capacitors could be used to replace a lead acid batter in a scooter?
No it won´t replace it. Maybe if you use ultracapacitors
Yes i have. This video is probably a hoax. Ultracaps or super caps are rediculously expensive and aren't cost effective. I can imagine using large value 200 volt electrolytic capacitors will do the job just fine and probably last alot longer.
Maybe if you only want your scooter to travel about 5 meters before it runs out of power.
More like 0.1 metres and a big spark xD
3:38 yes the apple is now safe.
You know,to solve the problem [hey,ludic science] can you please make a video about plastic classification???🙂🙂
genius
Can you just tear the wrap ....
Let's see how strong it is...
it's stuck on my Wang how do I get it off?
A propane torch should take care of it.
we in India use it to laminate our cricket bats
if the transformer heats, will the PET melt or change its shape or stay the same?
If the transformer gets hot enough it will melt it and eventually could catch it on fire if the transformer can get hot enough to boil water minimum. Safe to say if it gets that hot you will have far worse things to think about.
Dark Alchemist thank you
good user
Here is the glass transition temp of Polycarbonate - 147 °C so before that temp it stays hard.
I thought PET are carsinogenic???
GF......Perhaps if you eat them...?
No, PET is not cancerogenic
heating certain plastics could release cancer causing toxic gases .. not an ideal solution for encapsulating food.. anything is fine 👍👍
