Has Copenetro ever been used with any object besides coins?

I decided to answer my own question by doing a check of the askAlexander database. In the June 1971 issue of _M-U-M_ on page 35 we read:
-----quote-----
When I first saw Copenetro, I found it to be one of the most worthwhile investments for sensationalism and dramatism in magic, but for kids, they were boredly (?) fascinated. This may have been due to presentation, but after watching Mark Wilson do the same trick, musing a dollar bill in a paper clip, I devised a new and novel approach to the effect employing this bill-in-clip idea. It's a cute kid routine and brings laughs from the on-watching adults, so here it is and have fun!
-----unquote-----

I'm surprised that a dollar bill folded and paper-clipped would work in the Copenetro. But obviously it did.

So I wonder... what other uses could the Copenetro be used for? Maybe a card effect using a torn corner?

I was just able to buy a Bob Kline Copenetro in the secondary market and am awaiting its arrival. Having read that the reliability of the coin arriving in the shot glass is sometimes less than 100%, I am wondering if anyone with experience with this device has any recommendations for the optimal size (height and diameter) of glasses to use to improve its reliability. Someone previously commented on this I believe and logically, it would make sense that a shot glass with nearly the same diameter of the covering glass would ensure that the coin finds its way into the shot glass? I am also wondering if glasses made of another material, for example acrylic or plastic, would be less likely to break and still able to produce the desired sound? Any insights or tips would be appreciated. Thank you.
Eric.

I have experience with the Leap effect. This is a walk around copenetro effect. I found that using a tapered shot glass, the mouth is wider than the bottom, works best. I used an acrylic tumbler for the covering glass. This is so the quarter doesn't break the glass. This might work with your copenetro as well.

Hello eric,

You'll most likely find the tone you obtain with a GLASS glass is much more desirable than with Acrylic. It was not uncommon for the original outer glass to break. However most replacements, being standard real-world drinking glasses, last a long time. If you find the correct size from a non-magic source I suggest you buy several just in case.

You'll probably have to shop around a lot to find suitable replacements (unless you contact a magic retailer/builder like George Robinson @ Viking/CW). The magic retailer(s) will be considerably more expensive per glass.

Enjoy your Copentro!

Julie

Years ago, I assisted the local magic shop in finding a new glass for Copenetro. I had to visit 10 stores before I found a glass that would fit perfectly on the stand.

To answer Amatole's question, the answer is very simple to missing the shot glass. You just have to hold the stand perfectly level upon activation. Then it hits every time. You also should not move it side to side or up and down. That is why it is best performed with an assistant, but it can be done by the performer. Remove a coin from the coin stand. You will be already holding the stand with glasses in the opposite hand. Throw the coin (?) into the air, follow it path with your head and eyes. Look at the stand and glasses you are holding. They hear a clink, clink. Repeat with the other 3 coins. Then set the stand down, remove the glasses and pour the 4 coins from the shot glass into the larger beer glass.

The glasses are made by the largest drinking glass manufacturer in the U.S.

Bill, are you referring to Libbey? Do you have a record of their item/part #?

Thank you Mr. Hegbli. I too would love to know which company makes the glasses you refer to and if possible, the mouth and bottom diameters of both the covering and the shot glass which will work best with my Copenetro if you could please provide them. Thank you and thanks Julie for the follow-up question.
All the best.

I remember making many, many trips to thrift (resale) stores to find a couple of appropriate glasses. :)

I found mine through a Barware supply company. The original glass is a pilsner glass. If you find a Barware supplier that has Pilsner glass, simply
contact them and ask for the OD of the glass mouth. Usually they will want you to buy at least 1/2 a case of them (6). I simply put my remainder
on ebay as replacement glasses for 3.00 each.

Hope this helps....OOPS Hi Julie! How is your Summer going?

Kindest Regards,
Jake Jr.

When I have had an opportunity to play around with the Klein Copenetro if I figure out what glasses work best in terms of size and quality, I will share my findings with others who may have similar questions to mine. When my purchase of the Coin Odyssey has been completed and I have ascertained what works best with it (hopefully the glasses it comes with will be easy to source should one break), I will also share that information. All the best.

A-OK Jake!

F.Y.I. The glasses we found were not the Pilsner type. Each is a heavier "almost" straight up drinking glass, but fits into the Copenetro (AKA Copentro) groove and works well with much less concern over breakage as compared to the original equipment glass.

The coins fall into the shot glass almost 100% of the time. We've also found little 1 1/2 ounce dessert glasses (four in a pkg. for $1) from the dollar store about the same height as shot glasses, but heavier glass, work well, too. These seem to NEVER break like the shot glasses do occasionally.

...and that's the rest of the story. :)

I broke out my graphing calculator and attempted to compute "Almost 100%" and it kept giving me Error, LOL. Just kidding 99.9% with you Julie.
The glasses Julie is describing are probably better as the Pilsner style I have is bottom heavy when inverted over the top of the shot glass and more
prone to tipping while holding the base.

The original glass was a bowed shape for the narrow bottom to the wide mouth. They were a form of beer glass at the time. I am sure the dealer that sells Copenetro would supply additional glasses.

The one I found at the time was a fluted glass very thick slanted sides, and very thick throughout. It worked and fit perfectly. Back in the day, these were very common glasses found anywhere. Plastic kind of made them difficult to find, but I believe they are still around. Retailers just don't carry them these days.

There's another way to perform Copenetro without using any expensive mechanical props - just sleight of hand and chutzpah. The advantage (besides being very inexpensive to build and perform) is that a spectator gets to examine the glasses as he holds them in his hands to catch the last coin that flies through the air. Also you can use four (or more) different coins from different countries, different sizes, different metals, etc.

Hi Julie. My Copenetro arrived yesterday without any instructions. I have ordered the Bob Kline book on Copenetro from Viking for $8.00 and it will apparently ship after August 19 as I guess they are on holiday. I am of course eager to get started with my Copenetro which came with both the shot glass and covering glass intact. The base has four keyhole type openings which I see have a spring in them. This is, I assume, the mechanism I must set to trigger the release of the four coins. I am hesitant to play around with the Copenetro in case I damage it but am wondering if you could please send me instructions as to how to safely set it so I can start to experiment with it? If you insert four quarters into the slots in the base, does that automatically set the mechanism? I have seen the photos of Copenetro on one on Ebay which show the base with the four small holes and with small silver coloured projections protruding from them which I am guessing would then be pushed in individually to release each quarter? I also read somewhere something about needing to use a coffee stir stick to set the mechanism?
Any help you can provide would be appreciated, in a PM so as not to break any Magic Café revelation guidelines.
Thank you and all the best.
Eric.

Hi Eric

First off, my Copenetro(s) utilize American half-dollars. I've never tried other coins. The device to depress/set the springs is a wooden tongue depressor cut in half so there is a straight across end that will fit into each of the four topside slots.

By pushing this flat edge down into a slot, a rounded metal end will protrude out the bottom. Using your fingers you will manipulate this rounded metal end down the narrow channel into a position at the extreme end of the channel. The fact that the rounded metal end is larger than the channel keeps it in place.

When you want the coin to "appear" in the shot glass, your finger pulls the rounded metal end back towards the wider section in the channel and the concealed coin is literally "shot" into the shot glass!

Both of mine are early original Bob Kline props. I don't know what, if any, changes have been made along the way. My advice is to wait until you receive the manufacturer's instructions before experimenting.

PLUS it wouldn't hurt to keep on the look-out for replacement glasses. :)

Have FUN!

Julie

Thanks very much for the information and the advice Julie. I will heed both and restrain myself until my booklet arrives. In the meantime I will review your earlier posts and do some glass shopping just in case.
All the best.

I am curious about your opinion on Copenetro performance.

Years ago while hanging around Martin's magic shop in Detroit, I played with a Copenetro.

I did a routine with a visitor to the shop. I made the coins disappear while another held the set.

This other was an experienced Copenetro user.

He found the trick better to use as a penetration effect.

He said he used the coin stand to do the coin business but apparently pressed the coin against the larger glass.

Then the coin appeared in the shot glass. He would disassemble the set to show the glasses normal.

This was repeated four times.

Just curious what you (anyone) think.

I worked in Toledo Ohio at Carothers Magic Studio, the owner, Ted Carothers would demonstrate the same way, as a coin penetration and not an appearance.

I remember visiting Tannen's as a kid in the late 70's early 80's and Tony Spina did Copenetro in the shop one morning for some of us kids hanging out. We were all just mesmerized. RIP Tony

My bought-new-in-1962 original Kline Copenetro finally wore out the bottom plate, and became
unreliable in action. I used a computer CAD system to design a new replacement plate, and had
several new plates made from laser-cut stainless steel. The new plate works great, will last
a long time, and will be trouble-free. The new plate is easy to install in place of the old plate.

If there is interest from other Copenetro users, I can make them
available at a reasonable price. Is anyone here interested?
