What it looks like when you pour in the food dye.

Hi everyone! My name is Elena and I am this week’s Junior Scientist. For my experiment, I am going to show you how to make your very own shaving cream rain cloud. Make sure that if you try this experiment at home you are wearing some old clothes or an apron so you don’t get dirty as this activity involves food dye.


You will need…

  • Shaving Cream / Shaving Foam (not gel)
  • Jar half full with water
  • Food Dye 
  • Gloves and tray (optional)


  1. Spray shaving foam on top of the water in the jar.
  2. Pour food dye on top and watch it come down like rain at the bottom of the jar.

Hi everyone, my names Dominic and I am this week’s junior scientist.This week I did the bouncy egg trick.


You will need:

  1. A glass
  2. An egg
  3. Vinegar

What you need to do:

  • Step 1: Get your glass and put your egg in it
  • Step 2: Fill the glass till egg is covered in vinegar
  • Step 3: Wait for 1 to 3 days
  • Step 4: Take your egg out of your glass very carefully
  • Step 5: Gently rinse egg
  • Step 6: Bounce

Hi everyone, my name is Oscar and I am one of this week’s junior scientists.This is a science experiment I call How to make pepper jump?

This is a quick and easy experiment that is fun and will wow your friends. Remember to have parent supervision.


  • A plate or bowl
  • A balloon ( It doesn’t have to be helium)
  • Salt
  • Pepper


  1. Get out your plate or bowl and place it on the table.
  2. Scatter your salt and pepper across the plate. Make sure that the salt and pepper are mixed together.
  3. Rub the balloon quickly against your head back and forth.
  4. Blow up your balloon, if it is not already blown up and aim it over the pepper. Make sure it hovers over the ingredients, no touching them.
  5. Watch. If you have done it properly, the pepper should be jumping up and sticking to the balloon.


When you rub the balloon on your hair the friction caused by the hair and the balloon rubbing against each other causes the electrons from your hair to transfer to the balloon. This gives the balloon a negative charge. When you hold the balloon over the plate of pepper and salt, the pepper stuck to the balloon because the pepper has protons and a positive charge. Just like with magnets…opposites attract. The salt did not jump because salt is much heavier than pepper. Here is progressive photos below of me doing the experiment.


Junior Scientist – Sarina

Hi, Everyone! My name is Sarina and I am this week’s Junior Scientist. For my science experiment, I decided to do something to do with paper. I call it The Water Glass Magic. Make sure to have a parent supervising you before doing this experiment because it can get very messy.



  • A glass cup      
  • A Cardboard paper that covers the top of your cup.             
  • A bucket or a container.                                 


  1.  To begin your experiment take an empty glass and fill it half way. It is important to fill it exactly half way.
  2.  Take your cardboard paper and place it on top of your glass. Completely cover the top.
  3.  Carefully pick up the glass and put your container right underneath the cup you are holding.
  4. Then gently place your hand on top of the paper, then turn it over and remove your hand and see what happens.

The experiment appears to define gravity. The paper will fall eventually but the reason for this is the pressure outside the glass is greater than the pressure inside the glass. Which holds the cardboard and prevents the water from falling out.

Hi, everyone! My name is Fabian and I am this week’s ‘Junior Scientist’.

My experiment is called ‘Elephant Toothpaste’. You must have your parent’s permission to do this experiment. Elephant Toothpaste is a foamy experiment that looks like giant toothpaste fit for an elephant.


This is me setting up my experiment items! The materials I used is on the table.

This is me pouring the dry yeast mixture into the bottle which contains the hydrogen peroxide.

This is the ending result of my experiment on Elephant Toothpaste.

Hi, everyone! My name is Isla and I am this week’s “Junior Scientist“. For my science experiment, I decided to do something involving balloons. I call it “Amazing Inflation!” Make sure you ask for your parent’s permission before att.empting this.



  1. Baking Soda
  2. Vinegar
  3. Balloons
  4. Bottle/Container
  5. Funnel


  1. Pour vinegar into your bottle/container until it is approximately half of the way full
  2. Stretch the top of the balloon.
  3. Using a funnel put 1 and a half teaspoons of baking soda into the balloon.
  4. Stretch the balloon with the baking soda over the top of the bottle/container with the vinegar in it.
  5. Lift the balloon up so all of the baking soda is tipped into the bottle/container for the full chemical reaction.
  6. Slowly the balloon will start inflating.
