The Adgenda: "Lemonade" ads are a smart move from HSBC

Although the music is kind of creepy.

HSBC has put a cheery face on banking with a grade-school entrepreneur in their ads Lemonade and Lemon Grove.

The first video starts with the all-American summer image of a kid earning some pocket money from her home-made lemonade stand. Suddenly trouble arises when her latest customer doesn’t have any American change. Not to worry, turns out not only does our littelest businesswoman cover all major currencies, she also speaks Cantonese. Cue a bus full of new customers and an emerging local lemonade monopoly for international customers.

This raises some questions though. Does the dad get a cut of the profits? Is her home-made sign a lewd marketing campaign playing on the “innocent small business” image? Does she skim a few percentages over the exchange rate for herself? She’s obviously put a lot of thought into this. Fast forward to the next video and the situation has escalated wildly. She now has a lemonade empire stretching at least from America to France. She has also shown her true colours as a hyper competent polyglot with revenues large enough to fly to India to expand her supply routes.

What are the fathers thinking throughout all this? Are they really as naïve as the video leads us to believe and just play along with their daughters little game of merchant? Seems so as when the girl storms off for her next corporate adventure her dad is completely out of the loop. Did she only bring him as a cover story for border controls? If the story and her business follow this exponential growth the next video will feature a global mafia-like organisation, run entirely by twelve-year olds, with complete control of the world’s lemonade trade. The slogan of the ads confirm this: “In the future even the smallest business will be multinational.” Imagine the money she saves alone on using nothing but child labour. She has definitely not filed the official paperwork and who would prosecute a kid working at a street side lemonade stand? The rest of us will simply have to pray she doesn’t turn her attention beyond lemonade.

On a more serious note this is a smart move from HSBC’s side. Bankers have not exactly enjoyed a great image in the last decade, or for that sake, ever. A positive spin and a loveable character are standard for defusing blame and shifting attention. But it seems to focus a bit too much on presentation and too little on outcome. How did the advertisement team picture this play out? An executive wondering which bank could best suit his new takeover and bam his mind flies to HSBC because of an ad which seemed more suited as a storyline for one of his kids’ tv-shows?

Andrea Newman, global head of advertising and marketing communications, HSBC, said the purpose of HSBC’s “In the future” campaign aims to: “bring a sense of warmth, simplicity and optimism to inspire growth.”

The choice of music is terrible and kind of creepy though.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
