Richard moved his hands.
First find a square glass container from the wooden shelf and place it on the ring-shaped experimental table. Then lift up the flour bag you got earlier and pour it into the container. Then pour in an appropriate amount of water to keep the ratio of flour to water. Keep it around 2:1.
Stir with a glass rod until the flour and water are thoroughly mixed into something like a batter.
Richard looked at the contents of the container, touched his chin, and released a spell at the next moment, controlling the batter to leave the container, fly into the air, change form, and turn into a circular shield.
Stretching out his hand, Richard touched it tentatively. It was obviously very soft and could be penetrated easily.
Withdrawing his hand, Richard made a fist, increased his speed and punched out with greater force.
"boom!"
There was a muffled sound, and the batter solidified quickly, like a stone shield carved from a white boulder.
"Well-"
Richard retracted his hand, rubbed the painful fist surface, and stared expressionlessly at the dough that was slowly returning to its original shape. There was light flashing in his eyes as he thought about something quickly.
It is obviously feasible to use non-Newtonian fluids to make shields, there is no doubt about it.
However, it is absolutely impossible to use the current flour to make a shield and use it as a life-saving means. This is too childish.
This is only the most preliminary test. We will continue to improve based on this and experiment with more non-Newtonian fluids with higher density and superior properties.
We should try to use magic in it, combine the technology of modern earth with the technology of the current wizarding world, and let a shield play the role of "one plus one is greater than two".
"Then what's next..." Richard stared at the flour shield in mid-air and had a plan.
…
For the next many days, Richard was busy experimenting with various materials.
There are many types of non-Newtonian fluids, far beyond one’s cognition. In addition to batter and chewing gum, there are also tomato juice, apple pulp, potato pulp, molten chocolate, concentrated sugar water, condensed milk, egg white, and surimi and minced meat. All kinds of minced food materials are among them.
Of course, non-Newtonian fluids are not all about eating.
In addition to food, concentrated solutions and suspensions of polymers are generally non-Newtonian fluids, including but not limited to polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solutions, etc.
In addition, there are some construction materials, including but not limited to mud, coal-water slurry, ceramic slurry, paper pulp, paint, ink, etc.
What Richard has to do is to find and create as many non-Newtonian fluids as possible, and through a large number of experiments, determine which non-Newtonian fluid has the best effect, which non-Newtonian fluid combines best with magic, and which one A non-Newtonian fluid is more cost-effective...
finally…
…
Many divas.
Spell testing ground.
Richard was standing. On the ground next to him, there was a square container filled with a viscous liquid that looked like ink.
This is not a separate substance, but a mixture. In addition to some common materials such as gravel and carbon powder, there are also some materials for demonized creatures, such as the blood of the earth bear and the bone meal of the black-headed raven.
His eyebrows twitched, Richard bent down and looked at the liquid. Then he stretched out a finger, inserted it into the liquid, and pulled it hard to bring out long filaments. The filaments were stretched to a very long length without breaking and were very sticky.
"So… "
Richard flicked his fingers, and the free energy elements in his body surged, and the spell was released, causing the liquid to escape from his fingers and fly into the air, turning into a thick round shield. Afterwards, some muddy yellow liquid like grease emerged and covered the surface of the buckler - the power of the spell.
A dual combination of spells and non-Newtonian fluids.
"call-"
Richard stood up, took a deep breath, adjusted his body, controlled the air to protect his fist, aimed at the shield, and punched hard.
"boom-"
The shield made a sound, very softly.
Richard could feel that the force contained in his fist was forcibly dispersed the moment it touched the shield. The scattered force that followed hit the main body of the shield, causing the shield to quickly harden and be completely eliminated.
Richard retracted his fist and saw that the shield quickly returned to its original shape without any damage.
Richard blinked, and there was no surprise at all, because this was just the simplest test, and the second test would follow.
His lips slowly opened, and with a wave of his hand, Richard produced an ice pick. The ice cone doesn't look very powerful, but it's fast enough. It flies out like a bullet and hits the shield with strong kinetic energy and penetrating power.
"puff-"
The ice pick came into contact with the turbid yellow liquid on the surface, quickly tearing the film of the turbid yellow liquid, and hit the shield hard.
Then there was a "crash" sound, and it smashed into pieces against the hardened non-Newtonian fluid.
Richard was not surprised by this and conducted a third test.
Taking a step back to retreat a certain distance, Richard bombarded him with energy-shaping fire-like spells.
"Boom boom boom!"
After a few spells, although the shield's appearance was slightly damaged, it almost perfectly blocked all spell attacks.
So…
The final test!
"Da da da… "
Richard retreated, this time far enough away, preparing to attack with the strongest spell, salt and armor-breaking bullets, to test the effect of the shield.
You can also take a look at which one is stronger: the sword as an attack or the shield as a defense.
Who is it
Taking out the spell salt, Richard cast a spell to control the spell salt particles to fly out and attach to the surface of the shield. Then he chanted the incantation for a long time, and after preparing for a long time, he raised his hand and blasted out a gorgeous spell barrage.
"boom!"
The violent vibrations that had occurred before reappeared, and the sound waves and shock waves roared and spread in all directions, blowing violently across Richard's body.
Waiting for the sound to subside, Richard squinted and looked at the shield. It was seen that the entire shield had become shattered under the destruction of the magic salt. Only less than half of the volume on the front remained. It was obvious that the power exceeded the limit of defense.
Walking closer, you can see that not even a quarter of the volume of the back of the shield is preserved - it cracked under the stress caused by armor-breaking bullets.
In the contest between sword and shield, the sword clearly won—the sword pierced the shield!
From this point of view, perhaps the shield can be thickened and can be transformed into a more powerful shape in time for defense, but the sword can also become stronger. Moreover, under the principle of armor-breaking bullets, no matter how thick the shield is, it can still cause damage.
So... the shield will always be weaker than the sword
can you
not necessarily.
Sword and shield, attack and defense, are like two sides of the same coin. No one will always win, and no one will always lose.
The sword can rely on the principle of armor-breaking bullets to cause damage without penetrating the shield. So does the shield have no similar means to safely resist an attack that cannot be resisted
Like... reactive armor.
