The 'Inexhaustible Bottle' trick

The Inexhaustible Bottle is a classic magic trick performed by stage magicians. It dates back to the 17th century and has inspired many variations since. The trick involves a magician producing a bottle or kettle and asking the audience to name any drink—it can be water, beer, tea, or any other liquid. The magician then tips the bottle and pours out a glass of the requested drink. This process is repeated for different drinks, with the bottle seemingly producing endless amounts of liquid. At the end of the performance, the magician may break open the bottle to reveal various objects, such as coloured handkerchiefs, which are said to give the bottle its magical powers.

The trick is believed to have originated in 1635, when it appeared in "Hocus Pocus Junior: The Anatomie of Legerdemain" in London. In this early version, a barrel was used instead of a bottle, and it could produce three different drinks on command. The trick continued to evolve over the centuries, with magicians such as "Herr Schmidt," "Falck of Koenigsberg," and "Ludwig Leopold Döbler" popularising different variations.

By the late 19th century, the trick had become widely known and was even used by physicists to demonstrate hydrostatics. Magicians began to make modifications to keep the trick fresh and engaging. One notable variation was introduced by English magician David Devant as "The Obliging Tea Kettle," which involved using a kettle instead of a bottle. Another well-known variation was performed by Charles Hoffman, known as "Think-a-Drink Hoffman," who used a small bar and a series of cocktail shakers to produce up to 80 different drinks for his audience.

The Inexhaustible Bottle trick is based on two different concepts: the original "any drink" concept, where a single container can pour multiple drinks, and the "endless pour," where a seemingly continuous amount of liquid is poured from a small container. The trick relies on clever illusions and sleight of hand to create the appearance of endless drinks, often using hidden compartments and tubes to switch between different liquids.

Beer tapping physics

Beer tapping is a bar trick that involves hitting the top of a beer bottle with a solid object, usually another bottle, to trigger the foaming of the liquid within a few seconds. The phenomenon has been known for a long time but lacked a scientific explanation.

Javier Rodriguez-Rodriguez and colleagues at the University of Madrid in Spain decided to investigate the physics behind this trick. They filmed the evolution of gas bubbles within the beer as it was hit, using a high-speed camera and recorded the change in pressure within the liquid with a hydrophone.

Their findings revealed that the foaming-over process could be divided into three stages:

Bubble-collapse (or cavitation) stage:

When the bottle is hit, it generates a train of expansion-compression waves in the liquid that leads to the fragmentation of pre-existing gas cavities. This sudden increase in the interface area-to-volume ratio enhances mass transfer, causing the bubble volume to grow rapidly until the CO2 is locally depleted.

Diffusion-driven stage:

In this stage, the carbon dioxide (CO2) diffuses from the supersaturated bulk liquid into the bubbles, causing them to grow further.

Buoyancy-driven stage:

As the bubble clouds rise, the mixing in the fluid enhances the CO2 transport from the liquid to the bubbles. This creates a positive feedback loop where the movement of the bubbles causes them to grow, rise more quickly, and absorb more CO2.

This three-stage process results in the well-known foaming effect of beer tapping, providing insights into other natural phenomena such as the release of flavour-enhancing aerosols in sparkling wines and the catastrophic limnic eruptions in deep water lakes.

Beer marketing tricks

Beer marketing is an important aspect of the craft beer industry, especially with the recent boom in craft breweries. Here are some tricks and strategies to market your beer effectively:

Social Media Presence:

Craft beer enthusiasts often follow brands on social media to stay updated and engage with the latest product releases and events. It is essential to go beyond just posting pictures of your beer and include content that showcases your brewing process, team, and brand story. Running contests, engaging with followers, and turning popular posts into targeted ads can also attract new customers.

Local Partnerships:

Word-of-mouth marketing is powerful, and partnering with local restaurants, vendors, and businesses can help spread the word about your brewery. Offer discounts, donate beer, or collaborate on events to get your brand out there. Local community events, fundraisers, and meetings are also great opportunities to showcase your beer and venue.

Unique Selling Points:

Focus on what makes your brewery unique, whether it's the use of rare ingredients, creative label designs, or a one-of-a-kind taproom. Highlight these aspects in your marketing to stand out from the competition. Additionally, create inclusive and diverse experiences to attract a wider range of audiences and drinkers.

Email Marketing:

Email newsletters are a great way to maintain customer relationships and provide exclusive offers and updates. You can promote new releases, events, and special promotions while also sharing insights into your brewing process and team.

On-Premise Strategies:

Incentivize customers to visit your tasting room or taproom by offering tokens for free or discounted drinks. Creating a positive experience and building relationships with customers in person can lead to increased brand loyalty and word-of-mouth promotion.

Brand Ambassador Programs:

Encourage customers to promote your brand by developing brand ambassador programs. For example, you can hold contests where ambassadors who receive the most social media likes while wearing your merchandise win prizes. This strategy helps you reach a wider audience and build a community around your brand.

These marketing tricks can help you effectively promote your beer, engage with customers, and stand out in the competitive craft beer industry.

Bar tricks

The Rolling Bill Trick

This trick involves an empty beer bottle and a dollar bill. The challenge is to remove the bill from underneath the bottle without knocking it over and without touching the bottle. The trick is to slowly roll the bill towards you, using the rolled-up part to keep the bottle upright as you remove the rest of the bill.

The Two-Finger, Dollar Bill Challenge

For this trick, you'll need two empty bottles and a dollar bill. Balance the bottles on top of each other with the dollar bill between them. The challenge is to remove the dollar bill using only your index fingers without knocking down the bottles. The trick is to place one finger near the lip of the bottle and use the other to make a fast, downward chopping motion, like a magician pulling a tablecloth off a table.

The Six Oranges Riddle

This one is a fun riddle to puzzle your friends. "There are 6 oranges in a bag. There are 6 kids in a line. Each kid in line is given an orange but there is still one left in the bag. How can this be?" The answer? The sixth kid gets one of the oranges still inside the bag.

Turn Water into Whiskey

This trick requires two shot glasses, one filled with water and the other with whiskey, and a playing card or a sturdy business card. Place the card on top of the water glass and use your pointer finger to press it down, forming a seal. Carefully flip the water glass upside down on top of the whiskey glass. Then, slightly pull back the card to create a small space between the glasses. The whiskey will float into the water glass, and the water will sink into the whiskey glass.

Spin a Straw Without Touching It

Grab a beer bottle and a plastic straw. Bet your friends that you can spin the straw on top of the bottle without touching it. First, rub the straw on your clothes to create static friction. Then, balance it on top of the bottle and move your finger in a circular motion around the straw. The static energy will spin the straw, making you look like a magician!

The Free Drink Lottery

Write down one friend's name at the top of a sheet of paper, your name in the middle, and another friend's name at the bottom. Rip the paper into thirds and place the pieces into a container. Bet your friends that you can pick your name out of the hat every time. The trick is to feel for the paper with two rough edges, which will be the one with your name!

So, the next time you're at the bar, impress your friends and maybe even get a free drink or two with these fun bar tricks!

Beer-related magic tricks

Another variation of the "Inexhaustible Bottle" trick is known as the "Magic Funnel". This version uses a two-walled funnel that holds liquid between the walls. The magician pours a small amount of liquid through the funnel, but it continues to pour when they lift their finger from a hole on the handle.

A more modern beer-related magic trick is the "Chop Can Beer" trick, which is a classic of close-up magic. It involves a chop cup designed to look like a beer can, where a small ball appears and disappears beneath the can.

For those looking for a more explosive performance, there is a party trick that involves creating a foamy eruption from a beer bottle. By tapping on the top of the bottle, a compression wave is created through the glass, which results in the formation of bubbles and an impressive display of foam.
