We suggest you do a very simple and original experiment to surprise your child. This is a magical baking soda Christmas tree. It is a simple and fun experiment to teach children the reaction of certain materials to contact with others. We tell you everything you need to do it.
- Baking soda
- Green food coloring
- Disposable pastry bag
- Red glitter
- 2 glasses
- Plastic baby bottle (optional)
- Crystal bowl
1. You need half a glass of baking soda. Add a little water, but very little, and stir well with the spoon. You will see that the texture is still practically powdered bicarbonate.
2. Now find your green food coloring. It will give color to our Christmas tree. As long as you add a little less than a half teaspoon of food coloring, it will do. See when you stir it what texture and color your mixture acquires.
3. Now is time to add the red glitter. The tree will be much more festive. Stir well. Well, you need the other glass. Do you have the disposable pastry bag nearby? You put it in the glass with the tip down and cut everything that is left over. It only has to occupy the height of the glass. Make sure it is securely attached to the glass.
4. Put the mixture you just made into the pastry bag baking soda, water, food coloring and glitter. Squeeze the mixture well and see how it acquires a cone shape, thanks to the shape of the pastry bag. Put it in the freezer until the next day.
5. What is it already shaped like a Christmas tree? You see? Well, it was time to put the experiment into practice. Find the bowl, and carefully cut the plastic sleeve that covers the tree. Be especially careful with the final part, as it is more delicate.
6. Now comes the vinegar turn. You can pour it on the tree directly or use a little vinegar that you pour into a different pot like this one. And now comes the funniest part: pour the vinegar onto the baking soda tree without fear !! See how it reacts to contact with baking soda!
Explanation of experiment: This happens because they are reactive materials. In contact with each other, they form a product, a different matter. The acid of the vinegar in contact with the bicarbonate base produces water, sodium acetate and carbon dioxide. Fascinating!
