Hi, Nice tutorial!I just have one question:Won't sunglasses reflect the cards and reveal them to other players?

I like the idea!Instead of recharging it, can we just replenish the water?

it is dc, and it will take longer.

This the most beautiful circuit I have ever seen

I have a different way of shooting the marbles. I use the pointer finger of my left hand as a "catapult" and hold the marbles in place with the thumb and pointer of my other hand. To launch the marble it just let go of it, and it goes flying off.

I love playing marbles!

no, don't.It will burn your hand, your tool, and if you are pouring straight from the bottle, the whole thing will spontanoisly combust.

Use everclear.That is 190proof 100% ethanol.You will have to pay liquor tax, though.

The coin is to regulate pressure.Without the coin there would be too less pressure, and if there is too much the coin starts shaking and venting it, preventing the whole contraption from exploding.

Try HEET or ethanol

I have made many alcohol stoves, and not once have i rotated a blade.I just stab the can and start cutting.

Fill it with fuel and throw in a lit match

Bang!

Just do this outdoors, it may overheat or burn up

If you are concerned about poisoning, you should replace the denatured alcohol with any drink that has more than 80% alcohol.This will come for a higher price, and is illegal in some places, so just be careful where you take it.

Yes, that candle type thingy is a great stove for regular use, it is also called a buddy burner. If you fill it to the brim with wax, it will burn for hours! ( I have tested it)

In step 9 the picture shows a great mistake.There was some fuel on the floor, and it all caught fire.In some cases the flames are invisible and can be accidently stepped on and result in extreme 3rd degree burns.Take down that image and replace it with one that shows the correct safety procedures.

A coffee filter is not powerful enough on its own.

thanks.

Why can't he just make it for fun???

These are safe when handled carefully.Store them in a nice container and keep them for use later.

Yes, this kind of stuff is very dangerous.It should only be operated outdoors.

If it is too high, there is more distance between the fuel and holes.This can cause oxygen deprivation, and not let it burn properly.If you put some cotton as a wick to help the fuel climb up, the stove will work!

Wow, what a cool spiral!If you don't have methanol, you can use ethanol ( in the form of denatured alcohol or rubbing alcohol)I live in India, so I have to use rupee coins!

Nice!This is such a useful trick!Some staplers have a hole at the side of the compartment and you can see the red color through that too!

Hi, This is a nice tip, but it would get even nicer if you added pictures of the driver.

Making oobleck isn't too time consuming.It takes around 15 mins to make.

Cool!If I find iron filings to buy anywhere this is the first thing I will make!

There are 3 reasons.1: For education2: For fun3: To reduce plastic wasteThis is not for sale.

I have used a few pics that were not mine, but only to give an example of the materials needed.I don't think it is allowed in contests.

What a great Instructable!I will definitely try this!

This hub is not capable of transferring data, as it has no data wires.

Maybe the ps4 has built-in usb protectors.Try some other device, maybe a powerbank, old computer, camera, or even a phone!For the phone you will need a usb a-c converter, or a usb a-b, depending on the phone.

It automatically charges from the usb itself, before destroying it.

What is you wanted to destroy someone else's computer?

Amazing idea! I am suprised this didn't win the grand prize!

Not sure, but sounds like a very accurate explanation! : )

Thanks!

search for "moving optical illusions" on google and you will see many more.

yup, that's an optical illusion.there are many more like this too!

Cool hacks!

: )

Stop motion?I love stop motion!

Thanks!

This is a great idea!I have a few suggestions about some more stuff to add:All of these won't fit at a time, so choose the according to what you may need.1. A Swiss army knife will be great too, as it has all the blades, can openers and screwdrivers all in one.2. You could also add a loud whistle, if you got lost you could whistle for help.3. Tweezers (for splinter removal).4. Ointment is useful.5. Hand sanitizer, if there is no clean water to wash your hands.6. AAA, or AA batteries, for bigger torches you may have.Great instructable!
