If you fancy science but you don’t have the necessary conditions to conduct some of the more serious experiments, there are always the DIY ones. The fact that you can do it yourself at home doesn’t minimize the fun factor at all. In fact, these home experiments can be a lot more fun and entertaining compared to the more serious ones. We have a list of simple experiments with fun outcomes and an easy setup. Also, most of these experiments can be done with less money than you think. Affordability is one of the factors we paid attention to while making this list.
Mentos and Coke
We all watched the famous YouTube videos of people conducting this simple experiment. It’s a lot of fun and the resources you need are minimal. All you need to have is a bottle of Coke and some Mentos. Before doing this, make sure you’re doing it in a place where you won’t get into any trouble for spraying coke everywhere. Scientists have a never-ending debate about what’s happening and why does this reaction occur, but there’s a favorite theory among the sea of theories.
Scientists believe that the tiny perforations on the surface of Mentos cause the molecules from coke to react with the imperfect micro surface. The combination of carbon dioxide and microparticles on the surface of the candy results in a breathtaking geyser of soda. It’s great for entertaining kids at parties, and it costs just a few bucks.
Make a floating egg
This can also serve as a magic trick for kids on birthday parties. We all know eggs sink when you put them in a glass of water, right? Well, the situation changes with one simple trick – add salt. Besides the fact that the results of this experiment are truly fun, you can also pick up a thing or two about the density of liquids. All you need is an egg, a glass of water, and salt. Fill the glass with water until it’s about half full. Add a lot of salt (at least six teaspoons), and stir. After that, carefully (it’s very important no to mix the two liquids together) fill the cup with plain water.
The last thing you need to do is lower the egg and watch what happens.
Tornado in a bottle
This is also one of the simplest things you can do with common objects found in your household. All you need for this experiment is some dish washing liquid, a bottle, water, and some glitter. Fill the bottle with water up to three-quarters full. After that, add a few drops of washing liquid and sprinkle some glitter in as well.
The glitter is going to help you see the “tornado” within the bottle; it’s the only purpose of it in this particular experiment. Put the cap back on, flip the bottle upside down, and spin the bottle in a circular motion until you see a vortex forming. This is a good example of how centrifugal force works.
