The sucker is dish shaped, when pressed against a smooth surface the air is forced from beneath the sucker.The rubber makes an air tight seal and the air pressure outside is greater than the air pressure beneath the sucker, thus forcing the rubber sucker to 'stick'.

How does sellotape work?

Sellotape works by using an adhesive that sticks to surfaces when pressure is applied. The adhesive is usually a pressure-sensitive rubber resin that creates a bond between the tape and the surface. Once applied, the adhesive keeps the tape in place until it is removed.


What is sticks rubbing together an example of?

Sticks rubbing together is an example of friction, a force that opposes the motion of two surfaces in contact. When sticks rub together, the friction between them generates heat and can produce sparks, which is why rubbing sticks together is a traditional method for starting fires.


What force that acts between two sticks when rubbed together?

When two sticks are rubbed together, the force that causes them to stick together is friction. As the sticks rub against each other, the surface roughness creates resistance, generating heat and adherence between the two surfaces.


Why does tape stick best to dry surfaces?

Tape sticks best to dry surfaces because the water on wet surfaces interferes with the adhesive's ability to create a strong bond. Dry surfaces allow the adhesive to adhere more firmly, creating a stronger and longer-lasting bond between the tape and the surface.


What are two things observed in nature that are the result of adhesion?

When water sticks to surfaces like glass or leaves, forming droplets or films, this is a result of adhesion. Geckos are able to climb vertical surfaces due to the adhesive properties of their toe pads, which enable them to stick to surfaces through adhesion.
