No. The sensors don't have that kind of range.

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.

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.

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

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

Try HEET or ethanol

Bang!

Just do this outdoors, it may overheat or burn up

Fill it with fuel and throw in a lit match

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.

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!

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!

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.

What a great Instructable!I will definitely try this!

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

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

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

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.

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

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

Thanks!

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

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

Cool hacks!

: )

Stop motion?I love stop motion!

Thanks!
