this looks like a great mothers day/grandparent gift/ teacher gift idea. Lots of options with flowerpots, buckets, etc to put it in and with the types of flowers or stems to use and filling in the pail.
for hand sanitizer! LEGOs suspended in a liquid soap dispenser. Fun to put out at a LEGO party or everyday use in your kids' bathroom! I'd probably search for a cuter dispenser, maybe more geometrical, but still such a cute idea!
