On the first Monday of each month, unless it is during Victorian public school holidays, Science Works holds an even called Little Kids Day Out. It is designed for children 5 and under to enjoy the facility without the normal "big kids" to compete with. On this day there are no school groups booked in and there are special appropriately aged activities on.
My husband and I took Mr 5 and Mr 3. They had a fantastic time, as did we. This may be a hands on science museum primarily for children but there is a lot for adults to do here as well.
The only issues we had were with parking, or the lack of it, and the massive line to get in. The centre opened at 10am. When we arrived at 10:30 we had a decent walk once we found a park back to the entrance and a 20 minute wait in the ticketing line. There were also more people who wanted to go to the puppet show then there was space for. The staff wisely added an extra unscheduled show to cater for this.
