Hello my little poppers,
Can you believe it’s the 1st May already! May is always a busy month of tests in school but thankfully the only test you have to worry about is today’s Friday test 🎉 hopefully you have still been learning your spellings each week, doing your meanings sentences, either written or orally and doing a Friday test. I haven’t set another test on Mathletics as a few people had problems getting access to a computer on a specific day so keep going with your New Wave Mental Maths books.
I’m sure you are wondering why I called you little poppers above! Well it’s because today’s Red Room experiment is set to pop the top off anything you’ve done all week 😆 I have uploaded a video that does all the talking for me so go and have a look at it now then continue reading the rest of my post.
Well did you enjoy that? I’m still not up for any presenting awards just yet but I’ll get better with practise. Did you like the sound effects from the cameraman? 😆 I hadn’t told him what was going to happen so he was a bit surprised!
So onto the experiment details. As the video explained this is a very fun experiment and something you can do quite simply at home using either the fizzy vitamins or some baking soda and vinegar. If you don’t have a small tube like mine your mum or dad might have an old camera film canister that you could borrow. Once you’ve got all the equipment you need get outside and have fun.
Now, just like on an aeroplane ✈️ first we need a safety announcement:
- When you are holding the tube always point it away from yourself and not towards anything.
- Never look straight at the lid of the tube in case it pops off. The amount of water you use with determine when the lid pops so you can never predict when it will happen.
- Make sure you have plenty of space in front of you for the lid to pop off.
- Make sure anybody out along with you stands well behind you and never steps in front of you.
- Keep all pets away as you never know where they are going to run and the pop and fizzing may frighten them.
- If the experiment doesn’t work, leave the tube down in a safe place and don’t open it for 5 minutes to ensure it isn’t going to pop unexpectedly. You can try it again after that.
That’s the fun part explained but what about the science? What exactly is happening in the tube? Why does the lid pop off? I mentioned a little about fizzing but what exactly is fizzing all about? When you are doing this experiment look in the tube after the lid has popped and listen very carefully. What’s happening? Put your hand over the tube. Can you feel anything happening? Please send me pictures or videos of this experiment if you do it along with your explanation as to why it happens.
I really hope you enjoy this one!
