No displacement can?

A displacement can is usually used to investigate Archimedes Principle. It is used to deliver displaced liquid into a waiting beaker for weighing.

However if no displacement can is available a beaker can give a good result if precautions are used.

Firstly some petroleum jelly is smeared under the 'spout'.

Secondly the small beaker used to catch the over flow needs to be close and under the 'spout' as shown in the diagram.
