Here's a fun exercise to explore historical inventions!
Imagine you're an inventor at any period in history and want to propose a new invention. The invention needs the funding and support from an investor.
Choose an invention from history, describe the invention, the physics involved and justify the invention, to try and win the funding from an investor!
As an extension, you could describe any limitations of the invention and any future possible upgrades!
Add at least one reference for where the information is from!

Are you tired of using 20 candles to light up your study? Are you bored of spending so much time replacing candles? Bored of cleaning candle wax? THEN TRY THE NEW: STANDING ELECTRIC CANDLE BULB!
You just wind the crank a little and the bulb will light up! Brightening your room and allowing you to enjoy what matters!
Thanks to the work of Thomas Edison*, we are proud to offer this brand new product! It works by spinning a magnet inside a series of coils. This induces an electrical signal, which is sent into the bulb. The bulb is a pressurised container with a coiled wire which heats up and gives off light when the electrical signal is sent to it.
This product surpasses normal candle light as it provides more light, for longer time with less effort required!** One Standing electric candle bulb will last you years, just replace the bulb after a week with a fresh one!*** Unfortunately, the colour of light is limited, but with your investment we hope to investigate different types of bulb and stand to suit whatever style you desire! see the following for more information: https://en.wikipedia.org/wiki/Incandescent_light_bulb

**compared to typical candle usage
***additional costs for replacement bulbs, discounts available for bringing back the used bulb
