I’ve just started with Mudpies to Magnets and my first experiment failed to deliver so I’m not sure about some of these ideas.
Some are also very prep heavy or unsuitable when you have an 18 month old running around. However there are a lot of experiments in here (more than you could ever use) so you won’t be lost for ideas and some of them will work I’m sure. Even my failed experiment generated an interesting conversation and so was not in vain. Plus it has a range of ages up to 5 so plenty of usage will be had I’m sure.
