Effect

Performer patters that Blindsight is the apparent ability to see colors and shapes which cannot be seen. You offer a simple experiment. You introduce 4 ungimmicked colored cards: Red, Blue, Green, and Yellow. These in turn are sealed into 4 opaque envelopes and mixed so that the spectator doesn't know which color is in which envelope. You ask him to point to any envelope. Free choice, no magician's force of any kind. You hold it up and ask him what color he thinks is inside. Assume he says Blue. You write "Blue" on the envelope. This is repeated 3 more times with the person freely pointing to any of the remaining envelopes. Each time he states the color he thinks is inside and the performer writes it on the envelope.

Performer fans the envelopes out allowing the person to see the names written on each envelope. Magician states he only needs three envelopes for the first part and for the person to remove one envelope and place it off to the side. Let's assume he discards the envelope with the word Yellow written on it.

The other three envelopes are opened one at a time, the spectator has correctly guess what colors were in each envelope. This is pretty amazing in itself but the kicker is still to come.

Magician says nobody could have known what envelope the spectator would discard off to the side. The spectator, NOT THE MAGICIAN, picks up this envelope and opens it. Of course the correct color card is in it, but wait; there is a slip of paper in it and it reads: "THE YELLOW ENVELOPE WILL BE THE ONE YOU DISCARD!"

The magician can then show the other envelopes are empty, in fact all the envelopes can be examined.

Here are the facts:

NO Two-Sided color cards
NO Nailwriters or Boomwriters
NO Secret Writing
NO Switches
NO Sleights of any kind
NO One Ahead or One Behind Methods
NO Gimmicked Envelopes
NO Magnets
NOTHING SECRETLY ADDED OR TAKEN AWAY
Color Cards are not gimmicked in anyway
Only 4 Cards are used.
The choices are completely free. As clean as it gets. The handling is designed in such a way that spectators and magicians will be unable to backtrack and discover the method.

Another reputation maker that is priced way too low. Complete with color cards, envelopes, marker and all needed gimmicks to make this work.

My Dog Is Obsessed — Long-Lasting and Worth Every Penny
The Benebone Wishbone is hands-down one of my dog’s favorite chew toys. He cannot get enough of it. The real chicken flavor keeps him interested, and the wishbone shape gives him a solid grip from any angle. What stands out is the durability. My dog is a strong chewer, and this thing holds up far better than most toys on the market. No soft spots, no chunks breaking off, and no mess—just a tough, long-lasting chew that keeps him busy. Made in the USA is a bonus, and the medium size works great for a wide range of breeds. If you’ve got an aggressive chewer or a dog who goes nuts for flavored bones, this one is absolutely worth having in the rotation.

Great dog chew lasts a while, enjoyed by most every dog
These bones are great for a few small, yet significant reasons. Bottom line up front: They're great and a dog owner would be well served to pick up one or two of these as a long term chew toy your dog is almost sure to love. 1) The first being the odd shape of the bones. The shape enables the dog to pick up the bones with ease rather than some of the more flat bones or chews which can lead to a struggle and frustration. The three prongs and the elevated middle portion alleviate this concern. 2) These bones aren't ground material shaped into a bone shape, they are tough, plastic-like substances. They have a very subtle aroma of the flavor they are supposed to be (bacon, chicken, etc) but are completely safe for the dogs to munch on. The best part of the bones being this substance is that they last quite a long time. 3) The bones are lightweight and won't hurt you if you stub your toe as you walk around the house barefoot. 4) Dogs seem to love them. Only the most picky or reclusive dogs will ignore these bones.

Good size, lasts a long time
Dog likes these. She has her moments when this is only chew toy she wants, and spends days gnawing on it. She likes these bacon and chicken flavors. I like the fact that there is no squeak. This is a good size for full size Aussie, and I also like that she doesn’t “throw” these at me, she lays on the couch or floor and chews. They help to keep her teeth clean from plaque and tartar, so to me they are very functional. This is 4th or 5th buy again, so I wouldn’t buy again if she didn’t like. It does take a while for her to chew to point of needing new, since I keep variety of chew toys for her.

Awesome!
**update: we have had this toy for over a year! I have found one other con. Once chewed if you step on it you will immediately drop to the floor in agonizing all encompassing pain or (my personal favorite) say every dirty curse word you have ever heard while clutching your destroyed instep. BUT even though this chewed bone is the demon child of a LEGO and a race car to step on my dogs still love it, still chew it and we haven’t had to replace it yet! I have an insane chewer where toys usually last us less than 24 hours. It has become almost impossible for us to keep up with toys because of how expensive it has become. This toy is not only insanely durable but she has not left it alone for the 3 days we’ve had it. I was concerned that being “chicken flavored” would mean stinky or sticky and I was very pleasantly surprised that it was neither! It doesn’t leave a stain once chewed, it doesn’t smell, and it doesn’t have a weird coating on it. The only con so far is that due to it being so durable and hard it makes a loud noise when dropped on the tile or hardwood which made her nervous toward it at first but now that she’s started working on it she could care less about the noise. Super happy with this purchase and will 100% buy more in various sizes for our other pups.
