Have you ever tried an experiment that can be played with your children by buying a balloon? Come and feel the charm of science experiments.
5 balloon mini experiments, and children stay at home for a day.
Experiment one
Dancing balloons on pushpins
Material preparation: balloons, pushpins
Experimental procedure:
Prepare a balloon and a pushpin, and gently touch the balloon on the pushpin, and the balloon "bangs" and explodes.
Then prepare a bunch of pushpins and press the balloon hard. You'll see that no matter how you press it, the balloon won't explode and you can even dance on pushpins.
Experimental principle:
Stressed knowledge. There is only one pushpin, the pressure is strong but the contact area is small; when many pushpins, the contact area is large and the pressure is small, so the balloon is not easy to break.
Experiment two
Soda bubbles blow balloons
Ingredients: plastic bottle, apple cider vinegar, funnel, balloon, soda
Prepare a small half bottle of apple cider vinegar; pour the soda through the funnel into the balloon.
Slowly put the balloon on the mouth of the plastic bottle, pour the soda in the balloon into the plastic bottle, and you will see a magical scene!
After the vinegar and baking soda react, carbon dioxide gas can be generated, and balloons can be blown.
Experiment three
Not afraid of fire-burning balloons
Material preparation: water, balloons, candles
Prepare a blown balloon, gently place it on the candle for less than a second, and the balloon explodes.
Then, fill the balloon with water, take it to the candle and burn it, the balloon does not explode.
The water inside the balloon absorbs the heat of the candle flame, so the balloon does not explode. However, if the balloon is constantly heating, and the heat exceeds the amount of water inside the balloon that can absorb it, the balloon will still explode.
Experiment FOUR
Orange peel juice fried balloons
Ingredients: balloons, orange peel
The balloon is full of air, tightens its mouth, then takes out the fresh orange peel and squeezes out the juice against the balloon.
Next, take a closer look and a magical scene will happen!
Peel juice such as orange oranges has a dissolving effect on balloon rubber, which will make the rubber thinner and eventually make the balloon explode.
Experiment Five
A balloon that can run
Material preparation: plastic bottle mouth, glue, cd
Cut the plastic bottle mouth from the plastic bottle and attach the bottle mouth to the disc with glue.
When the glue is dry, take out a balloon full of air and put it on the bottle mouth.
A balloon trolley that can run around is done.
After releasing the balloon, the gas in the balloon will slowly run out, which forms a push that pushes the disc slowly until the gas in the balloon runs out.
These balloons are small experiments
Mom and Dad hurry up and take the kids to play!
Tips
As far as possible, it is up to Mom and Dad to complete the operation
Children can just observe
