If it is one thing my nephew adores it is science. Mainly weather and the science behind it but any sort of experiment, projects, YouTube videos etc he loves! Well for his birthday the theme this year is (you guessed it) SCIENCE! So in the spirit of things we (the family) have all been asked to come up with an experiment to preform at the party. Oh? What have I come up with?.. Good question!
First thing that came to mind was of course the tornado in a bottle. He is obsessed with learning everything there is to know about tornadoes so in turn it would be the perfect experiment to go with. My fear is that it probably was already taken by someone else and I didn’t want to risk it. Next was homemade lava lamps. This is when you “OOOooo!” “Ahhhh!” in excitement. Kidding.
Well that one also fell through so I continued my hunt until one afternoon I was watching a video on Instagram and ran across some experiments (I believe the video was on 5.min.crafts page). We will call it the “candle trick” came across and it looked simple, portable for my hour drive and the ingredients for the “trick” were items that could be found in my home.
Here is what you will need for the experiment:
- Candle (I had tea lights)
- Lighter or matches
- 2 glasses
- baking soda
There weren’t worded instructions to the video, so this is what I take from watching it and putting it into words.
- In one glass, mix together a little baking soda and vinegar. You want roughly equal amounts of each, like 2 tablespoons each.
- As the reaction is occurring pour off the invisible gas into the 2nd empty jar while keeping the liquid in the jar you are holding (the mixing jar).
- Place your hand over the jar or cover the glass with plastic wrap to store the carbon dioxide until you are ready to extinguish the candle.
- If you are ready to extinguish the candle, Simply pour the gas from the glass onto the candle.
How it works?
When the baking soda and vinegar are mixed together they produce carbon dioxide. The carbon dioxide is heavier than air so it stays towards the bottom of the glass. When you pour the gas from the glass onto the flame of the candle, you are pouring out the carbon dioxide which will sink and displace the (oxygen-containing) air surrounding the candle with carbon dioxide. This in turn extinguishes the flame.
Pretty neat eh? Simple yet cool enough to wow kids of the younger age.
