IS THERE chemistry in a lunchbox? ... that is one of the questions to be answered at IT Science Fair, which takes place on Sunday next.
The creation of prehistoric necklases, amateur rockets and some fantastic experiments are just some of the other highlights.
Visitors can become an archaeologist for a day, view a static display of model aircraft, look at life in your own garden, become an electronic engineer for a day and look at nature under a microscope.
Some 5,000 visitors are expected to attend an event which has gone from strength to strength.
It provides a kaleidoscope of colour and excitement to mark the beginning of Science Week 2012.
Science teacher at St. Clare's, Manorhamilton, Graham Hewston, is taking part in the Fair again this year.
His demonstration 'Chemistry in a Lunchbox' takes place at 12 noon, 2pm and 4pm.
'Rocket Man' Colin Fitzsimons, of the Irish Rocketry Society, will give a lecture on amateur rocketry in Ireland: 'From Donegal to Space.'
This lecture is one of the nightly public lectures, raning from the Northern Lights to septic tanks to bird watching.
IT Sligo's annual Science Fair is the largest free event for families in the North West and boasts an action-packed programme.
Discovering the science behind the magic is a key theme for all age groups.
"You can make your own prehistoric necklaces, build an Xbox game or examine the chemistry behind hip-hop dancing.
"There will be events to suit very young children as well as those with some understanding of science," said Dr Jeremy Bird, Head of the School of Science at IT Sligo.
