Eps 1: Rocket lolly
The Rocket lolly is a classic ice lolly that has been around since the 1960s and is beloved by many in the UK. It consists of red, white, and blue layers, each with a different flavor; cherry, raspberry, and lime. The lolly was created by an employee of a company that produced ice cream, in response to a request from a customer for a patriotic-themed ice lolly to celebrate the moon landing. The Rocket lolly soon became a huge hit and remains popular to this day. Although there have been some variations over the years, such as a tropical version with pineapple and raspberry flavors, the classic recipe is still the most loved. It is seen as a symbol of British summertime and childhood nostalgia.

To start off, let's talk about the history of rockets. The first recorded use of rockets was in China during the Tang Dynasty in the 9th century, where they were used for fireworks displays. It wasn't until the 20th century that rockets were developed for space exploration. The first successful rocket launch was by the Soviet Union in 1957, with the launch of Sputnik 1. This event marked the beginning of the space race between the United States and the Soviet Union.
Speaking of space races, let's talk about some of the most famous rockets in history. The Saturn V rocket, developed by NASA in the 1960s, was the rocket used to launch the Apollo spacecraft to the moon. It remains the largest and most powerful rocket ever built. Another famous rocket is the Space Shuttle, which was used by NASA from 1981 to 2011 for human spaceflight missions.
So, what makes a rocket work? Rockets work on the principle of action and reaction, also known as Newton's Third Law of Motion. The rocket pushes exhaust gases out of the back, and the exhaust gases push the rocket forward. This is why rockets need a lot of fuel: they have to eject a large amount of mass to move forward.
Now let's talk about some of the challenges of rocket engineering. One of the biggest challenges is making the rocket lightweight and aerodynamic. The lighter the rocket, the less fuel it needs to achieve orbit, which makes it more efficient. Engineers also have to design rockets to withstand the extreme temperatures and pressures of launching into space.
Another challenge is making sure the rocket stays on course. Rockets have to be able to adjust their trajectory mid-flight to reach their intended destination. This is done with small rockets, called thrusters, that can be fired in different directions to change the rocket's course.
Finally, let's talk about some of the exciting developments in rocket technology. One of the most promising is reusable rockets. By making rockets reusable, the cost of launching spacecraft into orbit can be greatly reduced. Another exciting development is the use of 3D printing to manufacture rockets. This technology makes it possible to produce more complex and efficient parts for rockets.
