# Try This at Home

Image: Discovery Education

Spin a raw egg on the counter and make some observations about the motion; then spin a hard-boiled egg on the counter and make some observations about the motion. They behave differently, huh? Why do you think that is? Leave your hypothesis in the comments section, then watch our virtual field trip to find out a whole lot more about eggs.

We are just one week away from our visit to Pearl Valley Farms to learn all about eggs and how they get from the farm to your table. It is an amazing process and the farmers at Pearl Valley will give you a behind-the-scenes look at the whole thing. This virtual field trip will be emceed by our own Lance Rougeux, who you might remember from the post from England on Pi Day!

If you can’t work it into your school day, you can watch the archive at http://www.discoveryeducation.com/events. (Archives are usually up a few days after the event airs.)

The raw egg will spin differently because it has the yoke and the yoke puts force on the shell and it slows it down while the hard boiled egg is solid and it will keep spinning

• Tashonea April 7, 2014, 6:37 pm

how u know?

• Larissa April 8, 2014, 6:30 pm

Logic

• Shane April 8, 2014, 1:02 pm

It is because of the liquid in the raw egg, and the hardboiled egg is solid inside. The liquid, and solidness in the eggs, change the course of gravity, causing the eggs to spin differently.

• Dedric April 15, 2014, 2:45 pm

I wish I can do this.

• Brian April 4, 2014, 3:37 pm

the white is liquid in the raw egg and because of that it will not spin as long, but in the hard boiled egg the white is solid, thus eliminating that problem.

• Shadow April 7, 2014, 7:25 pm

The raw egg won’t spin at all, the boiled egg will spin.

• Austin April 8, 2014, 5:56 pm

why does the liquid in the raw egg make it so it does not spin as long? more explanation but nice job bro:)

• A April 9, 2014, 8:01 pm

The liquid in the raw egg sloshes around inside of the eggshell, so it unbalances the egg’s spin and center of gravity, confusing the spin and making it topple over. The hard-boiled egg doesn’t have that problem, so it spins longer.

• A April 10, 2014, 2:42 pm

I meant to put “Anonymous” instead of “A”
I wonder why it did that…

• AshLynne April 4, 2014, 5:20 pm

I would say the raw would be heavier than the cooked one cause of the yolk and white in it so the cooked one would spin longer but slower. The reason it will be slower is it is lighter than the raw one.

• Natalie April 4, 2014, 5:55 pm

This is so cool!

• Austin April 4, 2014, 6:58 pm

the liquid in the raw egg is sliding around in the shell which changes the center of gravity which makes the egg fall over the hard boiled egg is solid so it will stay upright.

• Espree April 4, 2014, 7:36 pm

this was a very interesting espirement

• cook April 4, 2014, 11:43 pm

LOL

• Sophina April 5, 2014, 1:11 am

huh?

• George April 6, 2014, 7:11 pm

Tried this but the uncooked egg broke!

• Sarah April 6, 2014, 7:43 pm

The liquid in the raw egg is moving so it changes its center of gravity and fall. The hard boiled egg is solid and stands up straight.

• jacob April 7, 2014, 6:11 pm

cool

• Dachelle April 7, 2014, 6:52 pm

I think when the egg is cooked it thickens putting more weight on the egg.

• Alyssa April 7, 2014, 7:09 pm

there is liquid in the raw so its gonna going to faster ,but the hard boiled egg is a solid so its gonna be slower because of gravity. XD Thx for Reading

• crystal April 7, 2014, 8:31 pm

awesome lv experiments tryin it now

• summer April 7, 2014, 11:39 pm

Well actually my ray egg fell off the counter and had yolk everywhere!! what a big mess but I wont try again because the same thing might happen again and I don’t want to waste eggs sorry

• A April 10, 2014, 2:36 pm

I’m so sorry this made me laugh so hard.

• Larissa April 10, 2014, 7:19 pm

Summer is one of my favorite names I have ever heard.

• Asia April 8, 2014, 2:31 pm

LOL haHAHA

• Brian April 8, 2014, 4:00 pm

whether the white is solid or not makes no difference in the weight. it is the center of gravity shifting as the yolk moves around in the raw egg that makes a difference in the duration of the spin.

• Hayley April 8, 2014, 4:33 pm

We are actually learning about motion in class, so here I go. The raw egg spins and moves uncontrollably because a positive g-force is acting upon the liquid inside of the egg which pushes against the shell in whichever direction, which then pushes the egg in a different direction. Then the boiled egg spins in one area because there is an equal amount of weight spread among it, so it has no unbalanced g-forces acting upon it, meaning it will continue to spin in that one area. Eventually, Friction and air resistance will slow down both eggs to a stop.

• A April 10, 2014, 2:35 pm

Exactly, thank you.

• Serge April 8, 2014, 5:18 pm

The raw egg spins slow and the hard boiled egg spins fast because the liquid in the raw egg is moving around while the egg wants to spin and then the hard boiled egg is technically a solid and moves with the egg as one

• Ali April 8, 2014, 5:34 pm

because the liquid egg has not enough mass than the hard boiled egg. take a golf ball and a ping pong ball the golf ball spins longer because of the mass.

• alanda April 8, 2014, 5:51 pm

YEA

• Austin April 8, 2014, 5:53 pm

Alyssa the 2 eggs have the same mass the only diff is the hard boiled egg is solid. and what the heck does XD mean?

• A April 10, 2014, 2:33 pm

XD is a face, like an emoticon, but not. Look at it sideways, it’s supposed to look like an exited happy face. With closed eyes.

• Larissa April 8, 2014, 6:29 pm

I’ve done this before, it’s pretty obvious really. The liquid inside the raw egg sloshes around and unbalances it. The hard-boiled egg is solid all the way through so it spins like a top.

• Evan April 13, 2014, 5:30 pm

I did this in 2nd grade but now i’m in 3rd

• skylar April 14, 2014, 9:07 pm

hi

• Natalie April 15, 2014, 7:04 pm

The raw egg spin different because it has not been cooked so the yoke moves around more.

• MC April 17, 2014, 1:40 pm

I will try it at home but at my aunt Sandy and her farm with her baby chicks but I will tolally do it at home. LOL
