Rainbows are everywhere at the moment, as they symbolise the tremendous work and thanks we give to our fabulous NHS workers, so what better way than to open with a skittle rainbow experiment.
Place the skittles around the edge of a plate. The edge of the inner rim is best. The skittles can be arranged in any way, so this is great for the children to be creative and decide themselves. They can be arranged either in colour groups or a repeating pattern or even better…just random. The skittles should be touching for best results. Into the centre of the plate pour some water. This can be cold or slightly warm. Pour the water in gently and just enough so it reaches out and touches all the skittles at the edge of the plate. Now watch…. After a short while, you will begin to see the colours from the skittles dissolving into the water and after about 5 minutes a beautiful rainbow pattern will have been made. It’s really important not to jog the plate when this is happening as the colours can muddle up.
Points to remember
Carefully arrange the skittles around the edge of a clean, dry, and flat plate
Pour just enough water onto the plate so it touches all of the skittles
Take care not to jog the plate as the skittle create the rainbow
2. Storm in a jar
You will need an empty jam jar or a large glass, water, shaving foam, food colouring or watercolours, pipette or a syringe (Calpol or Nurofen syringe will do).
What if you could float into the sky and watch a storm happening from above the clouds? If you’ve ever travelled on an aeroplane, then you will know what it feels like to be above the cloud level and look down. This is exactly where you are going to go in this activity…well almost.
You will need an empty jam jar or a large glass. Fill it about three-quarters of the way with tap water. This represents the air. On top of the water, you are going to squirt some shaving foam to fill the rest of the jar. This is your big fluffy cloud. Next, either using food colouring or poster paints dissolved in a small amount of water, squeeze (using an old Calpol or Nurofen syringe) the colours into your shaving foam. After a few squirts, you will notice the shaving foam becoming full of extra liquid which will eventually burst through into the water layer below. The colours represent the rain.
You can make it authentic by just using blue colours or make a rainbow by having a selection. This quick, easy and delightfully mesmerising experiment is great for all ages!
Points to remember
Once the experiment is prepared make sure the food colour or paint is added gradually. It takes time for the colour to reach the water/ foam layer and you don’t want it to pour through too quickly.
Add the food colouring all over the shaving foam, trying not to concentrate it in just one area.
You will need a clear, empty plastic bottle with no labels, washing up liquid, vinegar (optional) and water.
Have you ever wondered why tornadoes do so much damage? Well in this experiment, using a few simple items from around the home we are going to create our very own mini tornado so we can see exactly what they get up too!
You will need a clear plastic bottle with a cap, half to 1tsp of washing up liquid depending on the size of the bottle, 1 tsp of vinegar (but not necessary) and water.
Fill your bottle about 3/4 full of water and add in 3-5 drops of blue food dye (depending on the size of your bottle and how dark you want the water to be). Add the soap and vinegar to your blue water. (Vinegar is only optional. It is used in the mixture just to lower the amount of bubbles after you mix the water and the soap). Make sure you don’t mix to quickly as you don’t want too many bubbles. Make sure the lid is nice and tight. Hold the bottle by the lid and turn it upside down. Swirl the container around in a smooth circular motion lots of times, increasing your speed as you go. When you stop you should be able to see what looks like a tornado or a Vortex. It will slowly disappear as it reaches the top of the container.
Points to remember:
Remember not to add too much food dye. You can always add more to deepen the colour.
To reduce too many bubbles once the washing up liquid is added, mix carefully.
Make sure the lid is on tight to reduce spills.
4. Dry-wipe wiggle
You will need a shallow dish or plate, a dry wipe marker and some water.
This experiment feels a bit like magic but there is some really cool science behind it too. Maybe you could impress your family or your grandparents on a zoom call with this experiment!
Find a shallow white dish or plate that is clean and dry. Using a dry wipe pen draw a stick man or write your name. You could fill the whole plate or draw more than one image to fill the space. Carefully and slowly pour some tap water onto the plate away from the images you have drawn and watch your plate come to life.
Can you make the images wiggle?
Points to remember:
Make sure the plate is white and shallow.
Ensure the plate is clean and dry before the experiment.
If you repeat the experiment always start fresh.
Pour the water slowly onto the plate away from the images so it doesn’t cause them to break apart.
Don’t leave it too long before you pour on the water.
The longer it is left the more difficult the images are to float.
New dry wipe pens work best.
You will need paper towels, 2-4 different colouring pens a plate and some water.
Chrom- a- tog- graphy is a really long word and it is used in some really useful ways in science. It is a science method that is usually used on a substance to separate it out into lots of different parts. It is often used by forensic scientists to help them to solve crimes and might be used to analyse blood found at a crime scene.
Collect one sheet of kitchen roll and fold it in half. Use some water-based colouring pens to draw the beginnings of a rainbow one cm up from the bottom of the paper towel. When you have coloured the beginnings of your rainbow, hold it from the top end. Add some water to the shallow dish and suspending the paper towel so the bottom just touches the water, you will begin to see it absorbing the water and travelling upwards. Your rainbow begins to inch towards the sky!
Points to remember:
Do not submerge the colours on the paper towel.
Hold the paper towel so the water level is just below the colours.
Only make your colour band 1 cm deep.
Once the water has stopped rising, remove the dish and leave the paper towel to dry.
6. Paper loop
You will need some scissors, a sheet of A4 paper and an adult!
Can you climb through a piece of paper without tearing it? For this activity, you may need help from an adult.
This is really cool so I’m really excited to share this trick with you! Most people are a lot larger than a piece of A4 paper. But in this activity, you’ll be able to squeeze through a hole in a sheet of paper. You might even be able to squeeze your adult helper through too!
Fold a piece of paper in half, lengthways. Put the paper on the table with the folded side closest to you.
Cut into the folded side, about 1 cm from the left-hand edge, and start cutting straight towards the far side of the paper. Stop cutting about 1 cm before the opposite edge, so you don’t cut all the way across the paper.
The next cut comes from the opposite side of the paper in exactly the same way.
Turn the paper around so the fold is away from you. Cut in around 1 cm from the last cut and stop about 1 cm before you get to the folded side.
Alternate between cutting from the folded side, and the side opposite. Keep your cuts 1 cm apart, and always stop cutting 1 cm before you get to the far side of the paper.
When you have finished, you should have a zigzag of paper.
Look along the folded side of the paper. You should have a series of loops of paper. Cut along the fold of each of the loops EXCEPT the first loop and the last loop. Leave these intact.
Remember, don’t cut the first or last loop!
Pull the paper apart, being careful not to tear it. You should have a large loop. Now try to fit yourself through the loop!
Points to remember:
Fold the A4 piece of paper lengthways
Keep the cutting lines 1cm apart
Only cut up to 1 cm from each edge and never the whole way across
When cutting the spine remember to leave the first and last loop intact or else you will cut open the whole loop.
7. Pepper explosion
You will need finely ground pepper, an earbud or cocktail stick, washing up liquid and a bowl of clean water.
This is really fun, simple, and quick and has caused many a gasp around the room when I’ve shown children. The only problem you’ll have is how many times they’ll want to repeat it!
You will need to fill a mixing bowl with water and sprinkle some pepper over the whole surface. Then carefully, using a clean end of an earbud, dab it into some washing up liquid and drop it into the centre of the water. Watch the pepper explosion!
Points to remember:
Always start with a clean and dry bowl.
Once the pepper or leaf boat stop moving across the water, the experiment is over.
Clean and dry the bowl between each go.
8. Runaway can
You will need an Inflated balloon and an aluminium can (coke/ sprite).
This experiment is so simple. Harness the energy and watch your coke can literally come to life!
Blow up a balloon (or ask your adult to help) and rub it vigorously on your hair to generate an electric charge. Pull it away slowly and see if your hair is attracted to the balloon. Bring the charged balloon close to an empty aluminium can. It is important that the balloon does not touch the can for the duration of the experiment but gets close enough to move it.
Points to remember:
Don’t let the can and the balloon come into direct contact.
Re-charge the balloon by rubbing it on your hair or jumper.
9. It’s an illusion
You will need water, vegetable oil and a marker pen, paper. An opaque cup and a penny.
Is your mind playing tricks with you with this fun illustration of illusions? Always a great way to entertain friends and family and quick and easy to do too!
1) Place a coin in a cup and stand back so that the coin isn’t in your line of sight. Add water slowly to the cup and watch the coin magically appear!
2) Draw two horizontal arrows pointing in the same direction on a piece of paper. Place an empty glass about 5 cm in front of the paper. Fill the glass with water slowly and bend down so the arrows are at eye level. Watch the arrows change direction! You can achieve an equally amazing effect by drawing diagonal stripes or cheques like a chessboard.
Wow! Optical illusions are awesome!
I hope you enjoyed these easy and fun experiments. Don’t forget you can order your science boxhere. The perfect gift for an inquisitive mini scientist! And follow us on Facebook, Instagram and Twiter for more fun and educational ideas.
