Happy April Fool's Day!

This morning I woke up and secretly made Jello in clear glasses (all I had was green, but red would have been better) and added a straw. Then this afternoon, I asked the boys if they wanted some juice. They, of course, said yes. As they tried to drink the juice, they complained that they could not get any. That's when I let them in on my joke! They love tricks and jokes so they thought this was fun and they liked it even better when I handed them a spoon!
