The simple discovery that a piece of wire mesh can stop a flame in its tracks saved the lives of thousands of miners.
This demonstration shows how a simple lamp made of gauze could contain the open candle flames that miners used before 1815. With the safety lamp, any potential explosions would stay contained and never escalate to dangerous levels (although mining remained an extremely dangerous occupation).
Watch the whole demo and hear the full story here.
How to get an egg in a bottle! You need a hard-boiled egg, a wide-mouthed bottle (just a bit narrower than the egg), and a match or strip of paper. As the paper burns, the air in the bottle warms and expands. After it goes out, the air cools again and contracts, and that draws the egg inside.
Density experiment. Salt water has a higher density than fresh water, causing the egg to float in it!
More about George Washington Carver:
Carver was born into slavery
Carver attempted to enroll at Highland College in Kansas but was rejected because of his skin colour
Carver saved money and enrolled at Simpson College in Iowa where he excelled in academic subjects and impressed many.
Carver was a talented artist.
Etta Budd was the name of his art teacher. She encouraged Carver to study Botany at Iowa State Agricultural College in Ames.
Carver was the first black student at that institution.
Carver impressed his professors and encouraged him to remain as a graduate student.
Carver obtained his Master of Agriculture degree in 1896.
Carver believed that he could use his training as an agricultural chemist to help improve the lives of poor Southern farmers.
The products Carver derived from peanuts range from cosmetics to dyes.
Carver also developed products from other plant products.

Artificial Water waves
I’m super here for magic and science meeting together in the best ways. I got this idea from a children’s science experiments book. Add a little bit of magic into the mix, and you’ve got a fantastic ward!
What you Need
Salt (epsom or sea salt seems to work best)
Gem water
String (I used jute twine)
Two cups
Something to heat water with
That’s it. It’s a super easy and super powerful ward, but it does take some time.
So what you need to do is create a super saturated salt solution. You’ll want to make a gem water that aligns with your intent. I used obsidian and black tourmaline to make my gem water (and I may have tossed a rose quartz in there too because I used that for everything).
Once your gem water is ready, you’ll want to heat it up, either in the microwave in a microwave safe bowl or on the stove. In order to make a super saturated solution, you need A LOT of salt. Keep dissolving the salt in the water until it won’t dissolve anymore. (This is why the heat is necessary. Salt dissolves quicker.) Keep pouring and dissolving salt until salt grains remain even with heat and stirring. I also recommend stirring clockwise in order to give it a little extra oomph.
When you have your solution, pour it into two separate glasses or cups. Get a length of string and place each end in the cups of salt water. Set the cups with the string between them somewhere it won’t be disturbed. (I set mine on the windowsill because easy access and hey, charged with sunlight and moonlight!)
It will take a few days, but slowly the salt solution will start to creep over the edge and along the string. When the water is gone/the string has grown salt crystals along it, take it out and place it somewhere in your room/house. I’d recommend by a door or window so that it keeps evil from entering.
You can also use this method with a paperclip, and grow salt crystals on a paperclip or pencil or any mundane item. You just need the solution and something to hang in the water. (You’d only need one cup for that!)
Be careful if you choose to add any sort of color or herbs to the solution. It is chemistry, so I’d mostly just recommend using salt and water. Adding other things to the water may impact the growth of the salt crystals.
I’ve also found that the leftover salt is an excellent cleansing agent. Add some to your bath/shower or even food (if you’re using some sort of sea salt/table salt/kosher salt). I rubbed a little bit on my third eye when I was having some psychic problems, and it definitely cleansed it out and protected it. I highly recommend using any leftover salt not on the string as a cleansing agent in any of your spells. It seems to be pretty a pretty potent protective agent. Salt is already potent in warding, and coupled with gem water it’s a pretty powerful ward.
Hope this helps! If you use this, let me know how it goes for you!
Rub your hands on the handles of a Chinese resonance bowl and you can generate a spray of tiny droplets. The key to this, as the name suggests, is vibration. Rubbing the handles vibrates the bowl, causing small oscillations in the bowl’s shape that are too small for us to see. But those vibrations do produce noticeable ripples on the water in the bowl. When you hit the right frequency and amplitude, those vibrations disturb the water enough that the up-and-down vibration at the surface actually ejects water droplets. The vibration of the bowl affects water near the wall most strongly, which is why that part of the bowl has the strongest reaction. It takes even larger amplitude vibrations to get droplets jumping in the middle of the bowl, but you can see that happening in this video of a Tibetan singing bowl.

Hi everyone! I'm Ashley P. and I'm a Girl Scout who wants to make a difference in the world. Currently, I've been working on my Gold Award Project, which is a project where Girl Scouts solve an issue in their community to earn the Gold Award. The Gold Award is the highest award a Girl Scout can achieve. In my project, I'm addressing the issue on how there are a lack of women in the STEM field by creating a program to do fun science experiments with younger girls. Also, I constructed this blog for parents and children to do exciting and simple experiments with their kids to spark a passion in this subject like what happened to me as a child. I hope you enjoy and try to accomplish the experiments I post! Also, please have adult supervision while completing these experiments.
