Sensory play is an awesome way to get your kiddos to try new things!  I enjoy applying it at home and in my work environment when I am in the classroom.  Pinterest is a site to look different types of  messy sensory ideas for you and your child to try out.  Slime, moon sand, edible sand, food play, and water play are just a small few ideas you can give a try.  Definitely take a look at Pinterest and google and try some new things!  Let your inner child out!
