How might I use these?
Great for forming a tight "lid" on boiling tubes. Makes an airtight seal to prevent contamination if you want to prevent gases entering. Also reduces the risk of spills when working with young children!

Supplied:
Five solid rubber bungs
What goes well with these?
Online STEM! (Small group STEM tuition online)
Top tips!
Wash in hot soapy water. Store dry.
If your experiment produces gas you may want to allow the gas to escape! (Unless you want to see how far you can launch the rubber bung, in which case Safety specs may be a good idea)!!
