Subsequent, seize your water and add a number of drops of meals coloring. This step is non-compulsory, nevertheless it makes the Oobleck further enjoyable and colourful! Stir the water gently till the meals coloring is absolutely dissolved.

3. Mix the cornstarch and water.

Slowly pour the coloured water into the bowl of cornstarch. Do that a bit at a time whereas mixing with a spoon. As you combine, you’ll discover the feel begin to change. It would look a bit lumpy at first, however hold stirring.

4. Get hands-on.

The extra strain you apply, the extra stable it turns into. Whenever you loosen up your fingers, it flows like a liquid. Oobleck is a non-Newtonian fluid, which suggests it doesn’t comply with the traditional guidelines of liquids. It’s stable when pressed and liquid when unstressed. Science is fairly cool, proper?

6. Clear up.

Oobleck can get fairly messy, so ensure you do that experiment in a spot that’s simple to wash up. When you’re executed taking part in, simply let the combination dry out, then sweep it up or vacuum it.

What can we study with Oobleck?

● Velocity vs. strain: What occurs while you transfer your fingers by means of the Oobleck slowly versus shortly? Attempt it out and see how the Oobleck reacts.
● Totally different shapes: Attempt rolling the Oobleck right into a ball and see if you may make it bounce or keep in form for a number of seconds.

That’s it! Now you’ve created your very personal Oobleck and discovered about non-Newtonian fluids. Oobleck is an superior approach to discover the properties of solids and liquids in a enjoyable, hands-on means. Plus, it’s an amazing excuse to get a bit messy and artistic. Bear in mind, science is all about curiosity and experimentation, so hold exploring and have enjoyable.
