You might have seen this simple science trick performed by the magicians. But could you believe that you can also prevent a balloon from bursting when pressed against a bed of nails? Yes its as simple then you think if you understand the underlying science behind the experiment. You can explain how multiple nails do not burst the balloon by following our steps and demonstrating this experiment.

Step 2: Blow a balloon and place it over the bunch of nails. Press it. But nails wont pop the balloon. Step 3: Similarly, insert a single nail inside the thermocol. Now when you place a balloon, it will blast. When balloon is placed on the bed of nails, the pressure is evenly spread across all the points, preventing the balloon from popping out. While on a single nail, balloon will blast as the pressure is concentrated on a single point.

My kids love science experiments and trying different science projects. One of their favorite simple science activities is the balloon skewer science experiment. It seems impossible, but with the right science know-how, you can learn how to poke a stick through a balloon without popping it. You can keep repeating this experiment until you run out of balloons. Blow up a balloon about half way.

Have the kids try to stick a skewer through the balloon without popping it. Some might be able to poke the skewer through one half of the balloon, but few will be able to get it all the way through. Try with a new balloon, but this time, dip the skewer in dish soap. This gives the skewer enough of a coating to keep the polymer chains of the balloon together, and you can poke the stick through both sides of the balloon near the tie and near the dark top of the balloon.

Try experimenting with other ingredients to see if they will also stop the balloon from popping. A piece of tape will help keep the balloon together, as well as other materials that reduce friction. What happens when you try using corn syrup?

A balloon is made up of molecule chains called polymers. Balloons contain elastic polymers that allow the balloon to stretch. Placing the dish soap on the skewer reduces enough surface tension on the balloon to allow the skewer to puncture the less-taut ends of the balloon.

The polymer chains close around the skewer, preventing the balloon from popping. But, if you try to puncture the balloon too quickly, or in the wrong spot, it will explode!

When the person's weight is distributed over several balloons, the balloons do not burst because the pressure is spread over a large area. As a result, each balloon only supports a small fraction of the weight. This trick only works if the balloons are not fully inflated. If this demonstration is done with fully inflated balloons, the rubber is already stretched out and is less elastic.

Balloons that are only partially blown up still have the ability to stretch. If the volunteer were to sit on one nail, it would be extremely painful. But if the weight is distributed over hundreds of nails, there is very little pressure on each individual nail, rendering the experience quite comfortable. The difficulty is when the person is in the process of lying down or getting up, since her weight is distributed on fewer nails, resulting in more pressure being exerted on each nail.

Describe the concept of weight and force distribution. How many people can stand on the board without the balloons bursting? Why did we use partially inflated balloons? What is happening to the balloons under the board? Why did the teacher say not to jump onto the board? If one student stands on one balloon, it will burst. Details Activity Length 15 mins. This is a recommended post-visit activity for a field trip to Science World. Objectives Describe the concept of weight and force distribution.

The balloon board requires TWO people to hold on to the sides at all times to provide stability. Likewise, at the end of the demonstration, have people come off board one at a time. Instructions Spread the towel out on the floor.

Balloon Boarding

Ask for two volunteers. Place all of the balloons on the towel. Position one volunteer at either side to stabilize the board. Invite another student volunteer to step onto the board. Remind him not to jump or bounce. Continue adding students until the balloons start bursting. Try fully inflated balloons. Could a student lie over the balloons without bursting them?Understanding the concept of pressure, particularly the relationship between pressure, area and force.

Bed of nails A piece of wood with nails driven through it such that the sharp end of the nail protrudes upwards. Pressure Pressure P is defined as the force per unit area, mathematically calculated by the equation:.

Bed of Nails - Cool Science Experiment

Step 1 Take one of the wooden boards and drill 98 holes for the nails to be pushed through later on. Step 2 Drill two larger holes on opposite sides of the wooden board, close to the edges, and glue the wooden dowels in the holes. Step 3 On the other wooden board drill two holes matching the positions of the dowels attached to the first board such that the board can slide along the dowels.

Step 4 Insert the nails through the 98 holes in the board at the bottom and make sure they are all level. Step 5 Place a balloon between the bed of nails and the upper wooden board and apply some pressure to the top board. Step 6 Demonstrate that a large force needs to be applied in order to pop the balloon. Once the bed of nails set-up has been prepared, blow up a clear balloon and show that the nails are sharp by popping the balloon with the leftover nail.

Slide the top board down the dowels and start pressing on the balloon. Show that the balloon does not pop easily, but keep pressing until it pops to show the audience there are no tricks involved, and that with enough force the balloon will still pop. Highlight that more effort was needed to pop the balloon when using the bed of nails than when a single nail was used.

Pressure depends on force and area. By increasing the number of nails, what is changing? The area. By pressing harder on the balloon, what is changing? The force. Does increasing the force on the balloon increase or decrease the pressure? Are the nails sharp enough to burst the balloon?

Yes, this can be demonstrated by easily popping a balloon using one nail. Why is it hard to pop the balloon on the bed of nails? The force applied is distributed over a larger surface area, thus reducing the pressure on the balloon. Will the balloon eventually pop on the bed of nails?Globule wonders Why do balloons pop? The balloon will only pop if the air finds a way to suddenly exit the balloon.

If children are old enough and if they are not easily scared, you may perform the experiment backwards by popping balloons different ways. For example, insert needles in balloons without applying adhesive tape or by exerting pressure on them. See our latest newsletter.

A paper spiral Water on a tightrope Volume.This Hot Air, Cold Air Science Activity is a great experiment to watch the effects of hot air and cold air on a balloon. This activity is a great opportunity for kids to talk about what they can see and why it is happening. Kids will absolutely love this activity and will see, first hand, what effects hot and cold air has on a balloon.

You will need two containers, one filled with hot tap water and the other with ice and cold water.

You will also need 1 balloon and a 1. The larger the bottle the more room the air has to push up and expand. Please do not use boiling hot water for this activity. Hot water from the tap will effectively work for this activity. During the following steps of the activity, provide children with the opportunity to predict, ask questions and discuss ideas. Science activities and experiments are a great opportunity to make connections between real life experiences such as the hot air balloon ride.

It encourages children to ask questions and promote scientific thinking such as making predictions, observations, comparison, reasoning, data gathering, experimentation and evaluation. When the air inside the plastic bottle is warmed, it expands and needs more space, therefore it stretches out the balloon.

When the bottle is transferred to the icy cold water, the air is cooled; it contracts and needs less space, so the balloon deflates. The mass of air remains constant inside the bottle, so this shows that the warm air requires more space and is less dense than cool air. So tying this into learning about weather because we just studied the water cycle and I think this is a nice segue way to finish the month with!
