Let’s make mysterious water that’s both hard and soft

[Fun Experiment] Hard yet soft? How to make water that seems like magic

Did you know that simply mixing potato starch and water turns it into a very mysterious kind of water? Put 200 grams of potato starch and one cup of water into a bowl and mix.

Just by mixing, you’ll create a mysterious liquid called a non-Newtonian fluid.

What’s so strange about it? Even though it’s like water, you can actually hit it.

Try bringing your fist down on it—it will feel solid, and your fist will stop before it reaches the bottom of the bowl.

But if you touch it slowly, since it’s still a liquid, your fingers will sink in.

Why not try making it for a science project?

♪ Mery-Go-Nyand – mgusqgi

A cute-looking strawberry roll cake squishy that’s perfect for a school science project.

Start by making the roll cake, then decorate it adorably with pink silicone whip! Experiment with color choices that make it look real and explore differences in texture as your theme.

It’s not only cute to look at, but also super squishy and soothing to the touch.

To make it even cuter, try adding strawberries, cookies, and pink pearls.

Displaying photos or the actual piece will surely convey the fun to anyone who sees it.

Let’s make a leaf vein specimen

[BCS Project] Let’s Make Leaf Vein Specimens! / Suzukake Science Day 2021

Let’s make a leaf vein specimen using leaves you can find around you.

First, bring water with 3 tablespoons of baking soda to a boil and add the leaves.

Simmer for about 15 minutes, then when the water turns brown and the leaves become limp, remove the leaves.

This softens the pigments other than the veins.

Next, rinse the leaves under running water and gently tap them with a toothbrush to scrape away everything except the veins.

Be sure to choose sturdy, relatively tough leaves for this experiment.

Let’s make rock candy

[Independent Research] Why Does Rock Candy Form? ~With Summary~ [Experiment Time]

Let’s try making sparkling, magic-like rock candy for a science project.

Prepare granulated sugar, water, sticks, wooden chopsticks, glass cups, liquid food coloring, and a pot.

Put the granulated sugar and water into the pot and simmer until it boils.

Wet the tip of the stick with sugar water and coat it with granulated sugar.

Pour sugar water and your favorite color of liquid food coloring into a glass cup, then sandwich the stick between a pair of chopsticks and set it so the stick doesn’t touch the bottom of the glass.

Cover with plastic wrap and leave it for 3 days to 1 week while observing.

Take photos and keep records to track any changes you see.

Let’s make transparent eggs

Summer science project: Make transparent eggs using vinegar [Research]

This is a simple science project where you just soak an egg in vinegar: “Let’s make a transparent egg.” Put an egg in a clear glass and pour in enough vinegar to cover the egg.

Then cover it with a paper towel and observe.

In a few days, you’ll have a transparent egg! The acidity of the vinegar dissolves the calcium in the eggshell, leaving you with a shell-less, transparent egg.

Do not eat the egg used in the experiment.

Ear age check with mosquito sound

[Ear Age Check] If You Can Hear This, You’re in Your 20s or Younger – “What’s the Difference?” [TBS]

Do you know what a “mosquito tone” is? A mosquito tone is a very high-pitched sound around 17,000 Hz.

Young people can hear it, but it’s said to become harder to hear as you get older.

By checking how high a frequency you can hear—or from what point you can no longer hear it—you can estimate your ear age! For a science project, how about playing mosquito tones for your family, friends, and teachers and gathering your own statistics? Animals may sometimes show cute reactions when they hear it, so if your pets cooperate, you might end up with some interesting research findings too.

Let’s try making ice cream that doesn’t melt

[Independent Research] Let’s Make Ice Cream That Doesn’t Melt! — With a Summary — [Science Sweets]

Ice cream is something you could eat every day on a hot day.

This experiment might change the idea that ice cream always melts quickly.

First, let’s start by making ice cream! The ingredients are almost the same, but for one batch we’ll add agar (kanten) or powdered agar.

When you place the ice cream with agar next to the one without it… amazingly, the ice cream with agar doesn’t melt.

Regular ice cream will start to melt little by little when the temperature is above 20°C, but the agar-added version won’t melt unless it’s heated to over 70°C.
