Publisher's Synopsis
Energetic twins Al and Lottie are always one step away from trouble. Al is experimenting to invent a time machine that can take mum back to when dad was still alive and she didn't have to manage the shop on her own. A time machine would also be really useful to get him out of trouble! As a young scientist who never gives up, Al is surprised to find that his experiments often have the most unexpected (and messy) consequences. This time, Al is looking to find the best shape for his time-machine capsule. So when Al, Lottie and their very naughty dog Einstein experiment with all the eggs in the fridge (meant for dinner!), they end up in a very sticky situation with their neighbours. Can they finish their experiment before mum finds out?
