HI Miss Florence,
This episode of Mythbusters is great, they are on the water and there, the wooden boat is floating thanks to uphthrust, because if there woulddn't be upthrust, the boat wouldn't float, and whales wouldn't float because they can't with their 100 or 200 tonnes!
See you,

Hi miss FLorence,
I watch mythbusters in my house because they do such funny things such as exploting cars and doing fantastic things, but I didnt waath this episoid. Its a good one. this example shows how upthrust works because the wooden boat pooshes the water and does not let the water come in. But when you add more wheit the boat does not float and sinkes.

I think this is cool the boat uses upthrust to make the air stay in the boat. Ive seen this happen once before in a movie this is cool.

Hi Miss Florence
The force of BUOYANCY is very useful for the ones who love to investigate about the water. The myth-busters program is about a guy who is with a wooden boat and the boat is a bit heave and because of the force of Upthrust or Buoyancy the boat could stay in the surface. That why I think ships that are SOOOOOOOOOOOOOOOOOO heavy can float on water.

Hi miss Florence :
This episode is very interesting, I cant believe that the force can keep 5 pirates aboard , now i know why do the boats keep afloat , thank you

Hi miss Florence,
This episode of Mythbusters is outstanding, because of uptghrust hte boat is floating and also because although the boat is very heavy it isnt more heavy than water. But when you add more weight the wooden boats sinks.

Hi miss Florence
This guys of mythbusters are always dooing weird and cool stuff.
Similar as the boat with air inside, I sometimes grab a Bucket put it over my head and sink into th water
Its amazing because I have air inside the Bucket.

Miss Florence:
This episode is fantastic!, it demostrates how the force of upthrust work!, here it demostrates by showing a boat that is floating thanks to upthrust, also like you can see when they put water on the boat, gravity pulls the boat down thanks to water!
Mythbusters are very intellingent!!, I saw then in TV.

I like allot the part the boat was in the other way and they could breath inside it. I had seen that in a movie called pirates of the caribbean. Also I laught when the wodden boat started to sink.

Hello Miss Florence:

In this video, the Mythbusters are using a boat like a submarine. The boat floats thanks to bouyance, if bouyance didn´t exist the boat would not float. the less amount of air that changes its size the bouyance is also going to change. Great video. See you in class!!!!

The Mythbusters are really cool I saw them once on Discovery Channel. The boat floats thanks to the upthrust if the upthrust wouldent exist the boat wouldent float.

FLORENCE,
IT WAS GREAT, i remember I saw it when i was small but i did´t understand anything. you can see when the boat sinks is because like it has water in it and round it that they work like magnets and try to join and if a man who weights 100 kg and gets in that boat it doesn´t sink but AProximately 100 kg of water in the boat might make it sink. I now that it is liters but, i dont know how to calculate 100kg in liters, sory. It was fun anyway to see it.
Thank you

Hello Miss Florence,
Although I couldn't understand a lot I understood a bit, here it is:
Bouyancy is the force that pulls the objects in water upthrust, depending in the material of the object. If you place a piece of metal it would sink, but if you place a boat with five pirates the boat would float. It is amazing, I didn't know this force existed. But if you pour lots of buckets full of water, and cover the entire boat, it sunks. The boat has his shape to help water pass throw the sides and do not sink the boat. The video was great, I didn't know the Mythbusters.

In this video I wached that they put a boat up side down and air stays on it because is a curved surface. you also explain us last class that wood float in water and metal no.I think that you can't do it on a flat surface because the air would escape from the boat

Hi Miss Florance

This video of Mythbuster was fantastic! I enjoyed it alot. Very good video. It is a video worth to be seen.

In this episode you can see a very clear example about upthrust. The boat made out of wood could float on water thanks to upthrust.
I learnt in scince and explored in the web to clear my dought, that the material named wood can float on water because it is less dense (lighter) than the water.

I didn't say Mythbusters. I think I should. This video is completly true, and I have pruved it. When I was smaller I had a boat like that one but smaller for my pool. And I played with my brothers that the boat (turned) was a submarine and the one who has inside had to look for the other ones in the pool.

Hello Mis Florence
Upthrast helped the boat float and support the weight of the mytgbuster. As the men put 45 bukets of water they could prove that the boat would sink because of Buoyancy. This works because if the boat underneeth has water and it to has water on top the boat would sink because the boat has two liquids surrounding it and the two are of the same material so thats how Buoyancy works.

Hi Miss Florence
It is gorgeous Mythbusters videos because they explain everything very detail and clearly so you can understand it perfectly. I understud that the boat could float because of Upthrust and That water displacement keeps up the boat with the same weight. Then that they pout some bucets of water inside and then it sinked.
It is Amazing I showed the video of the bug with surface tension to my father and he was shocked I think he really liked it.

The want to see if it is a myth that an upturned roeboat can be used as a submarine.
When the roeboat has too much h2o in it, it sinks.
But when it is upturned it doesnt sink.Boats dont have problem in keeping above water whiles they dont have to much h2o.
When the boat sinks it means that the buoyency was beaten.
When you go deeper the smaller the water turns.

This episode if MythBusters made me remember of when we were studying in class, and the examples you went giving us. I think that this video was very udeful to understand basically how upthrust works. Upthrust is the force that keeps something at the surface of the water. I love when in videos they give you clear examples to make you understand what you are talking about, very common in science! So im very pleased with the example of this video: A wooden boat being pulled up by the force of upthrust.

Hi Miss Florence,
This video is great, in this episode of Mythbusters they are on water, and the boat is floating beacause of upthrust. If there was no upthrust the boat wouldný float and any object woyldnt float also. I saw in the video that when you add water on the boat it sinks. It is very common because it goes down. And you can see it.

Hi Miss Florence,
I learned a lot with this wonderful video. It taught knew things and examples, but sometimes it reflected what "Upthrust or Bouyancy 1" said.
The boat doesn´t sink because there is a force that pushes upwards, in this case upthrust or bouyancy. When you throw water on the boat it sinks because interrupt the force.
See you,
P.D: I didn't understand the part when the man was in the water with a tube and bubbles came out of the tube.

Hi Miss Florence,
This episode of Mythbusters explains that buoyancy is the upward force of a liquid against an object. It is interesting that if the buoyancy that is against the boat is equal to the weight of the water displaced by the boat and the boat was designed to displace enough water to support 5 people.

In this video you can see a very clear example on upthrust. This boat made out of wood could float on water thanks to upthrust.

Something I learnt is that, bouyancy is the force that pulls the objects in water upthrust,but depending in the material of the object. If you place a piece of metal it would sink, but if you place a boat with five people in it, the boat would float.

I think that putting videos of the mythbusters its a very good idea. Because they show the video in a very funny way.

It was a ver good video.

Hi Florence,
I learnt that the boyency of a boat is determined about how much water it desplais or pushes out of his wet. Boyency is the upward force produced by liquid in this case water on an object. The weight inside the diggie (boat) is equal to the force of the buoyancy pushing upwards. It depends how deep you are.
