What just happened?
I think my experiment just did drop!'
What am I talking about? Well science of course!
Who doesn't like a fun experiment? Something to blow you and your friends away. Keep on reading because I have a couple of fun science experiments to show to you!
Dry Ice Bubble:
This experiment is fun to do with adults and kids! Add water to the dry ice, cover it with a layer of soapy water and watch your bubble grow, how big will it get before it bursts? Give it a try and find out!
You will need:
- A large bowl with a lip around the top (a smaller bowl or cup will work too)
- A strip of material or cloth
- Soapy mixture for making bubbles (water and some dish washing liquid should do the trick)
- Dry ice - one piece for a cup, more for a bowl. Places where adults can buy dry ice include large grocery stores and Walmart. Butchers and ice cream stores might have some too.
Please be careful with dry ice as it can cause skin damage if not used safely. Adults should handle dry ice with gloves and avoid directly breathing in the vapor.
1. Place your dry ice in the bowl and add some water (it should start looking like a spooky cauldron).
2. Soak the material in your soapy mixture and run it around the lip of the bowl before dragging it across the top of the bowl to form a bubble layer over the dry ice.
3. Stand back and watch your bubble grow!
I've tried this before and it is so amazing and fun to do.
Making invisible ink is a lot of fun, you can pretend you are a secret agent as you keep all your secret codes and messages hidden from others (like your siblings).
You will need:
- Half a lemon
- Cotton bud (or Q-Tip)
- White paper
- Lamp or other light bulb
1. Squeeze some lemon juice into the bowl and add a few drops of water.
2. Mix the water and lemon juice with the spoon.
3. Dip the cotton bud into the mixture and write a message onto the white paper.
4. Wait for the juice to dry so it becomes completely invisible.
5. When you are ready to read your secret message or show it to someone else, heat the paper by holding it close to a light bulb.
So why are you still sitting here? Go and try one of these! Or you could go and experiment yourself.
Bye! I'm off to Science class,
