Who On Earth Invented … The Pedal Bin?!
Continuing our series on enterprising inventors of everyday things we take for granted, Sally Anne asks …
Who on Earth invented…the Pedal Bin?!
You’re carrying something to the bin, your hands are full and you don’t want to spill it. Thank goodness for the pedal bin! Read on to find out about the inventor who tried to make life easier.
Ergonomics is the science of making equipment which fits and works with the human body. This basically means making things work as easily and as conveniently as possible. Dr Lillian Gilbreth was a keen inventor who believed in finding the easiest way of getting things done. As such, she invented a range of gadgets to make jobs easier, including the pedal bin in the 1920s. Now we have to admit, pedal bins aren’t very exciting, but Lillian’s life definitely was.
A Trip to Mars!
Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.
Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.
Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.
Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.
Carnivals Around the World
You might have heard of the carnival in Rio, but did you know that there are carnivals around the world – from Germany to Greece, USA to Italy?
Millie Slavidou explains where Carnival comes from on her blog
Long before the advent of Christianity, people held celebrations at this time of year. In Germany, they once looked forward to sending Hel, the goddess of the underworld, back down to her abode so they could herald the coming of the spring. In Greece, it was a time to worship the god Dionysus. With the arrival of Christianity, the celebrations continued, but changed in nature, gradually becoming more and more linked to the new religion. The Carnival is held in the period before the start of Lent, and Lent is the time when good Christians were supposed to fast, to abstain from meat
In the UK, we don’t celebrate Carnival, but we do prepare for Lent – that is what Pancake Day is all about, after all. Traditionally, pancakes were made to use up the eggs, fat, and butter, that were not to be eaten during Lent!

SCIENCE NEWS – What is Dengue Fever and Could Genetically-Modified Mosquitoes Prevent It?
Dengue (pronounced den-gee) fever affects between 50-100 million people each year, with around 25,000 people dying from the disease. It’s most common in south America and parts of Africa, and is also known as breakbone fever because it causes such intense pain in the bones. Dengue fever is a virus that’s spread by mosquitoes, and there is no vaccine or effective drug treatment to prevent or cure it.
How to Be an Inventor
Have you ever thought ‘There MUST be an easier way to do this’? If you have, you are not alone. People around the world invent and re-invent products all the time. Some of them are professional, and inventing is part of their job. Others are just normal people who had a bright idea.
There are many clubs and societies which you can join and learn to invent or develop your curiosity and talent for science and invention. All inventors start somewhere, and most of them start when they are very young. Young people have the best imaginations so if there is something you think is a good idea and you want to try and create, why not join up with other young creative people and work together.
