Description
Blind-sight Outdone (with gimmicks) by Devin KnightNOTE: Do not confuse this with the original Blindsight. This 100% new method will fool those who have the original trick. The performer shows four manila envelopes. There is nothing written on the envelopes, nor are they secretly marked. He shows them freely on both sides and points out the envelopes are opaque. The performer hands the envelopes to a participant; saying inside each envelope is a different colored card: Green, red, blue, and yellow.
NOTE: Do not confuse this with the original Blindsight. This 100% new method will fool those who have the original trick.The performer shows four manila envelopes. There is nothing written on the envelopes, nor are they secretly marked. He shows them freely on both sides and points out the envelopes are opaque. The performer hands the envelopes to a participant; saying inside each envelope is a different colored card: Green, red, blue, and yellow. The performer has the participant mix the four envelopes. This is so neither the performer nor the participant will have any clue to which color card is inside of any envelope.
The performer then asks the participant to hand him the envelope that he thinks contains the green card. The performer writes green on the front of that envelope with a black marker. This is done in full view, so the participant can see the word being written. This is repeated with the colors red and blue, with the performer writing those colors on the envelopes while the participant watches and sees the words being written. Nothing is hidden. One envelope is left in the participant's hand.
The performer asks jokingly, "Which envelope do you think contains the yellow card? (The participant says his remaining envelope.) This may not seem to be much of a choice; but it is a choice, as you kept that envelope for the last one. There is no way anyone could have known which envelope you would have left for last. I do not wish to touch that envelope, please continue to hold it for now."
The performer places the three envelopes with the colors written on them in a row on the table. Showing his hands to be empty, he picks up the envelope marked green and opens it removing the colored card inside. It is indeed green! The green card is shown on both sides and dropped on the table. The mouth of the envelope is squeezed open showing the inside. The spectators can see it is empty. This is repeated with the other two envelopes. Again, in both cases, the participant has correctly guessed the colored card inside. Three guesses and all of them correct! A perfect hit!
The kicker ending is yet to come. The performer recaps that he has not touched the envelope remaining in the participant's hand and that no one could have known which envelope he would leave for last.
"Obviously, the yellow card must be in that envelope. Please remove it. There is also a slip of paper inside the envelope. Remember, the other envelopes contained nothing but the colored cards; however, the envelope you are holding is an exception. Please remove the slip of paper and read aloud what is written on it."
Written on the slip is, "I knew this envelope would be your last choice."
At this point, the participant can examine all four envelopes and the colored cards. There is nothing to find. The ending is the same every time. There are no multiple endings.
BAFFLING BEYOND WORDS....LOOKS LIKE A REAL PSYCHIC FEAT...WILL LEAVE YOUR SPECTATORS DUMBFOUNDED!
Additional Facts
Many magicians who have the original effect will be puzzled by this new method. There is no equivoque or multiple endings used in this new version. There is no play on words, and the colors are written in full view of the spectators. The perfect effect, as described in the original Blindsight, happens every time! Nothing is left to chance. All the colors written on the faces of the envelopes are freely shown. The black marker is not gimmicked.
The strongest ending in the original Blindsight is when the envelope chosen for the finale has a prediction slip inside. This new version always ensures that a prediction slip is inside the last envelope for a climax. In the original Blindsight, the cards and envelopes could not be examined at the end. A strong point of this new version is that the participant holds all four envelopes during the routine. At the end, he can examine everything. There is nothing to find as the four envelopes and colored cards are UNGIMMICKED and there are no other hidden predictions. The performer is left clean.
NO GIMMICKED MARKER

NO SLEIGHTS

NO ONE AHEAD OR BEHIND METHODS
INCLUDES Two Bonus Effects you can do using this new method.
POKER TELLS OUTDONE: Do my Poker Tells effect, by letting a participant correctly tell you which cards are sealed inside opaque envelopes. An entirely different method from the original Poker Tells, as this version has no multiple endings. The same effect as Blindsight Outdone, done under the same conditions, but using 4 aces instead of colored cards.
MONEY SENSE: A very commercial effect in which your participant correctly guesses the value of 4 currency bills sealed inside opaque coin envelopes.
REVIEWS:
"Devin Knight has outdone himself again with Blindsight Outdone, which I predict will become an instant classic! Having the knowledge of the original Blindsight and its variants, I could not fathom how Outdone could be achieved. With a little practice, you will have another miracle in your hands. A real reputation-maker at a bargain price!"
- Robert Marsi
"I never thought that Devin Knight could top his Blindsight, but he has done so quite admirably with his new Blindsight Outdone. The effect will blow away magicians who know the original trick. The method is so devious and well thought out that it left me shaking my head in disbelief!"

Adds comfort and support
Color: Green, Size: Twin
I’ve been using this bamboo mattress topper for a couple of weeks now, and it completely changed the feel of my bed. My mattress was starting to feel too firm and uncomfortable, especially on my lower back and shoulders, but this topper added the perfect amount of cushioning without making the bed feel overly soft or saggy.
The cooling effect was one of the biggest surprises. I tend to sleep hot and usually wake up sweating during the night, but the bamboo-derived fabric feels breathable and much cooler than regular mattress pads I’ve owned before. It stays comfortable throughout the night and doesn’t trap heat like memory foam toppers sometimes do.
I also really appreciate the waterproof protection. It gives peace of mind without feeling stiff or making that annoying crinkling noise some waterproof covers have. The surface still feels soft, plush, and smooth. It honestly feels more like a hotel-style pillow top than a basic mattress pad.
The thickness is just right for pressure relief. It helped reduce the soreness I usually wake up with in my back, and I’ve been sleeping much more comfortably overall. The deep pockets also held securely on my twin mattress and didn’t slide around, even after moving a lot during sleep.
Another thing I liked was how fluffy and well-made it looked right out of the package. After letting it expand for a bit, it became nicely plush and evenly padded. The stitching seems durable, and it still looks great after washing.
If you’re looking for a softer, cooler sleeping surface with added waterproof protection and better support for aches and pains, this mattress topper is definitely worth it. It made my bed feel newer and far more comfortable without needing to buy a whole new mattress.

BDEUS Twin Mattress Topper, So Soft
Color: Green, Size: Twin, Color: Green, Size: Twin
Having purchased BDEUS products in the past, I was very looking forward to ordering the mattress topper made of viscose (a material derived from bamboo) just to see (and feel) the benefits of the material.
My concern about the material, viscose derived from bamboo, is that the process to manufacture the material can be chemically intensive leading to harsh smells. I can say the topper has no off-putting smells. The quality of the manufacturing is present as there are no loose threads/seams, the material has no defects, and the print is uniform. The use of the material also leads to increased durability while enhancing the topper’s breathability and cooling properties.
The topper is fitted meaning the topper will not come off the mattress very easily (even though you may need sheet straps if you are a wild sleeper). But the softness is wild, I mean this has to be one of the softest materials I have felt, and it feels very luxurious. Waterproofing and moisture-wicking is also a benefit as small spills are not absorbed into the fabric.
The topper is also very thick and plush, and while the product listing touts “Back Pain Relief” it may be too soft depending on how firm, or soft, you prefer your mattress. I have to say this is definitely a five-star offering from BDEUS. This topper is for my daughter but I’m going to order a queen-sized topper for my bed as the price is just right.

This topper has definitely provided me with better, more comfortable sleep.
Color: Green, Size: Twin
I recently tried a twin mattress topper made from bamboo-derived viscose, and I'm quite impressed. The topper is thick, waterproof, and offers excellent comfort, especially for those who struggle with back pain or sleep hot. The bamboo and polyester blend gives it a soft, cooling surface that's perfect for a restful night's sleep without the sweaty feeling often associated with memory foam.
What I really appreciate is its dual function. It's breathable, allowing for good air flow, and fully waterproof, which helps keep the mattress underneath safe from spills. This is especially useful if you have kids or pets.
The topper's thickness is just right—it provides great support without feeling too soft or too firm. It cradles pressure points well, offering relief to my hips, back, and shoulders.
The fluffy filling holds up well over time, maintaining its softness and support. It fits securely on mattresses, thanks to a deep pocket skirt that prevents any sliding or bunching. This topper has definitely provided me with better, more comfortable sleep.

Soft and comfy
Color: Green, Size: Twin, Color: Green, Size: Twin
This mattress pad is much thicker and fluffier than the one I had before. With I took it out of the package, it was vacuum sealed with a note saying to leave it out in the sun for 48-72 hours or fluff it up with a hair dryer. I put it in the dryer on medium heat, which worked nicely. The pockets are really deep on this mattress pad and it fits snug. You don’t really see the shape with a sheet on top. It feels comfortable laying on top of it. It doesn’t flatten much when I’m laying down, but I imagine over time it will lose fluffiness. Overall it’s comfortable and breathable.
