I came upon an interesting discovery after leaving my new WPT cards on the table directly under my room window. The cards which were relatively stiff (as all new cards are) became very soft after its prolonged exposure to the sun.

Has anyone had this experience before and is it more of a good or a bad thing?

Yes, Cards under heat for long will cause it to soften. Most stuffs actually will become soft. Its the matter of how much heat the object can withstand, take an example, ice cannot retain its heat elements, thats why it melt faster under heat or sunlight. Yes, you may say "its melt" not "soft", actually all objects will reach a half solid half liquid state, and this state is so called soft. and yes, if under extreme heat, the card will melt off, thats also explain y metal will become soft metal when under a low heat for long time, and become liquid when expose to it for even longer. :)

Hope you get the idea. And its not really good, depends on individual loh, i perfer stiff cards become of the hard feeling and the ability to create a stiffer snap sound when u snap the card. And when you riffle, it creates harder sound than weak cards, and its harder to get bend for tougher cards.

i believe its due to the glue within the card turning into a softer state.

:o

You mean the card will literally melt away if left in the sun for too long and into a liquid state? Didn't know that was possible :blink:

Theoratically cards are still made of paper, so the EXTREME state in which heat will cause it to be in will be combustion, aka BOOM! :P

Or maybe just burn?

so any idea how to make soft cards stiff?

i know if you soak paper in water and you sun dry it, it will become very hard... maybe i should try on cards

Actually I kinda like them soft... it feels easier to manipulate and performing passes are easier.

If I remember correctly, the same WPT cards turned back to its stiff state after i left it in a cool dry box under my table, so I guess you can do that..

Haha!!

No, it wont eventually melt off if u leave it under the sun for too long. All kinds of materials, there is a graph for it, the state change point, i think most of you study it in science.

For some materials, like paper, their state change from paper to liquid is clear to infinite, so it means, the state at which you see it melt, is impossible, unless u slow down the speed the world is spinning. So thats y u see it when into combustion. All of us know that combustion is due to the heat and the vapour in the air, which means, in vacumn, there wont be combustion. So since the state period of paper, from solid to liquid is none, it turns to vapour immediately, and this change of heat, will cause a sudden rise in the energy exchange, between the atomsphere and the object itself, which cause it to burn. Now, unless the whole body, or paper is under the same heat throughout the combustion, or else, you will see burning, because the heat between the burning point and the haven burn part is different. Thats explain flash pad. flash paper also use normal paper, but a paper under treatment. So the chemical inside this paper, will allow the heat, or its reaction to heat is very high, and cause the paper to combustion almost immediately, but it still wont be fast enough to eat up the paper immediately, even thought to u its immediate, but in terms of engineer, we talk abt nano sec, thats y, u will still see a sudden flame, but then its very fast.

Agree?

Then do the opposite as mentioned lor, stick your deck in the freezer :ph43r:

Nice try ning, but actually the method is very easy, u need to heat it up, using hair dryer or under the sunlight. And when its warm, put it into the freezer and let it cool down immediately. It might become stiffer, but the concequences will be that there might be thin lines of cracks looking around the deck if u try to bend and twist after u take out.

Actually Ning is almost right.

dun put ur cards in the fridge cause when its cold and u take it out, water condense on it and cause it to be wet...find a air thight box and put some active carbon to keep the cards dry and stiff

ribbon spread your cards in an air con room overnight.

wait, Doesn't that mean, that by theory, you can put your cards under the sun, then when its still soft flatten them under something heavy to make them flat again?

Haha!! I wonder whether it works.. Ya the coldness will make it stiff, but it become moist then, and then it will be sticky

I think the method of using carbon is good, absorb the moisture and it will be dry and stiff.

:ph43r: :ph43r: :ph43r:

Fellas. I was just kidding about sticking them in the fridge yo.

We are all just kidding. I mean, you actually believe the sun exist?!

Is the soft deck easier to spring/pressure fan? Lol.

Actually no, because its easier to bend, thus, if you apply too much pressure, it might bend but wont spring out. So, cant be too soft, cant be too hard. :)

LOL... you're so funny, can I adopt you as my little brother? Wuahahahaha... :lol:

hmmm.... i don't know if what i'm posting now is crap or what so forgive me if its stupid.

I learnt (in class jus now) that every thing has a line of plasticity. when force is acting on it and reaches it limit for plasticity, it will become soft and easier to bend. however, it will stil return to its original state but when it goes over the MAX limit. its a goner

:huh: :mellow: :huh:

hmm... actually it works...i tried it yesterday.

Oh my god. I'm a frikking science genius and I didn't even know it :blink:

haha the cards become smoother and softer, haha i tried it long ago, there was a post about ribbon spreading the cards in the air con room, i tried it, but i wanted to speed things up to i put my cards in a zib lock bag and left it in the fridge over night.

Dry Ice!! Hehe, anything, if you wanna adopt me as your lil bro. :g:

Haha, U guys are freaks man.. Anyway, i did mentioned abt the graph thing, like i say, everything got its solid, liquid and gas state. Science uses liquid, because liquid can be easily found, or represent in school.. Where else if i write plasticity, not all will understand, and not easy to make a soft plastic also.

The bend curve that was mentioned is the stress and strain curve, due to the energy given into the bend, it creates a similar effect to the sunlight thing.

What about silica gel? It absorbs moisture and is commonly used to keep DVD-Rs in tip top condition... could it work for cards?.. As in put them in an air-tight box with silica gel after extensive use. Does anyone think that the silica gel will effectively absorb the moisture from cards - sweat, oil, etc - and bring it back to its dry state?

Tried and tested. It works.
