Paragraph 1
Scientists from Macquarie University in Australia have made an exciting
about honey bees. The scientists found out why a bee's
keeps putting venom into a person's
after it leaves the bee's
. The scientists used high-speed
to film the tiny stinger, which is only two millimetres
. The video showed that the stinger works like a
. It has two small parts that move backwards and forwards. These parts push the stinger
into a person's skin to help keep the venom flowing. The lead researcher said the
of the pump was "unique". She hopes her discovery will help companies make tiny pumps that could give
to people.
