Want to find out your chances of winning the Lotto or discover if golf balls influence your game?
These and more than 470 projects are going on display this week at the Esat Young Scientist and Technology Exhibition in the RDS.
Visitors to the exhibition, open to the public from Thursday to Saturday, can view projects from almost 2,000 students.
The students will begin setting up their projects tomorrow and judging will begin on Wednesday. Award winners will be announced on Friday.
Some 120 students entered the competition under the new technology category which has been added to the usual categories of chemistry, physical and mathematical sciences; social and behaviour sciences; biology and ecology.
Projects on mobile phones are among those in the technology category. Research into the levels of radiation emitted by phones, their use by teenagers and their menace in society are among the projects. Use of the Internet for shopping and in business also feature.
A number of projects have also been entered on the subject of sport. Anna McCarthy of Loreto College Dublin tested golf balls for "bounciness" to see if it influenced the distance a ball travelled. Mark Egan of Colaiste Bhride, Co Wicklow, looked at the design of golf balls as an influence on their flight when played.
Drugs in sport, the dangers of training and straining and the future of the GAA are among the other sport projects.
Grace Keogh and Siobhain Perry from Loreto College, St Stephen's Green, Dublin, studied the effectiveness of deodorant by growing bacteria on it. Clara Mackey and Louise Laird from East Glendalough School looked rubbish which found its way onto the Wicklow seashore. Jason Barrington and Heather Minion from the same school discovered ways of killing zebra mussels.
Inventions and new ideas are a feature at this year's exhibition. Sarah Colclough, Niamh Keane and Clodagh Killeen from Colaiste Iognaid, Galway, built a pneumatic car which runs on compressed air. Other schools looked at ways of dealing with earthquakes and the power behind tornadoes.
Other interesting projects include a cure for acne, the physics of accents in Co Louth and a dust magnet.
As well as viewing the projects, visitors can also see laser and mirror demonstrations by the Institute of Physics in Ireland. A demonstration entitled "Musical Squares" will involve the use of sound effects and human and animal sounds.
The "Magic of Chemistry" involves experiments of cannon fire, colour changes and egg explosions.
Weatherman Gerard Fleming will discuss "The Forecast for the 21st Century" at a lecture.
The Esat Young Scientist and Technology Exhibition is open to the public from Thursday to Saturday from 10 a.m. to 5 p.m. There is an entrance charge of £5 (£2.50 for students and pensioners) and £10 for families of two adults and two children.
