3. Snow Storm in a jar- For this activity you will need a jar, baby oil, white paint, water, glitter and Alka- Seltzer. First of all, fill the jar with 3/4 of baby oil.
When you mixed the borax in with the water, you created a suspension. A suspension is a mixture that contains solid particles large enough to settle out. By mixing the borax into hot water, instead of room temperature or cold water, the borax stays suspended longer within the water.
As the borax begins to settle out, or sediment, it begins to crystallize. You’ll see this crystallization on both the bottom of the jar and, you got it, on your snowflake. The borax continues to sediment on top of the snowflake and on top of other borax crystals until you pull it out of the water the next morning.
In a bowl mix together very warm water and white paint to make white water. The amount of paint you need will depend on how much water you are using with the idea being to use enough water so that you can fill the jar almost to the top. Once mixed pour the white water into the jar and then sprinkle in the glitter. Wait for the glitter and water to settle at the bottom of the jar.4. Snow volcano- If you are lucky enough to experience snow during half term why not try this unusual fun experiment. All you will need is some leftover snow, bicarbonate of soda, washing up liquid, red food colouring, vinegar and a water bottle. You will need to add all of the ingredients to the water bottle except the vinegar. Create a whole big enough to place the water bottle in the pile of snow, but so the children can not see the bottle. Add the vinegar and watch the eruption! If it doesn’t work so well, add a bit more washing up liquid and vinegar. Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide, a gas which is the bubbles you see, these bubbles make the washing up liquid bubble up to give the reaction shown above. 5. Erupting snow- A fun experiment that will keep the kids entertained indoors for hours! For this experiment you will need bicarbonate of soda, shaving foam, blue glitter and vinegar. Firstly, you will need to pour the bicarbonate of soda into a large mixing bowl. Then start to add the shaving foam until it feels as thick as snow. You will then need to add the glitter and give the mix a good stir. Your kids can play with this for hours and make different shapes or even people. The next part is the best part- time to start erupting! Pour the vinegar over the snow and watch the magic happen. It’s so easy to do over and over again too! It’s also great fun to play with the foamy remains!
Once the water is settled it is time to make the snow storm! Take an Alka-Seltzer tablet and break it into pieces. Drop the pieces into the jar and watch what happens- a snow storm.
