If you are fortunate to have your grandparents still alive (that proves that you are still young!), then I’m sure you would like to give them something like Poppet. It definitely sounds similar to a puppet but it a plaything or entertainment product. It’s actually an aid for those who have to pop in numerous pills all through the day. This uncomplicated tool de-blisters pills from pill packs by pushing pills out from their pill packs, and storing to automatically pour the pills into a pill box or a hand. Older folks or arthritic pill users can use the Poppet to open pill packs saving time and unnecessary fiddling by combining pill de-blistering with pill pouring for faster and easier pill preparation.

Well it isn’t that high-techie gadget but I’m sure your granny or grandpa are gonna bless you for gifting them this tool that retails for £3.50 (about $7).
