If yours aren&#39;t yet convinced, make certain of it with these 50 off-the-wall, out-of-the-box activities. Share some silly fun, and they&#39;ll never see you as normal again.</p><ol><li>Take a flashlight into a dark closet in the daytime and practice making shadow puppets.</li><li>Teach your grandchild a tongue twister.</li><li>Try to catch coins off your elbow. Have a competition.</li><li>Buy a magnifying glass for you and one for your grandchild and look at everything with them.</li><li>Bounce a ball back and forth, with the number of bounces increasing each time. See how many bounces you can get before the bounces get so low that the ball can&#39;t be caught.</li><li>Wear pajamas all day. Then put on clothes for bed.</li><li>Make up a silly song to be sung to the tune of a song that everyone knows.</li><li>Play in the rain or play in the water hose with clothes on.

Take pictures.</li><li>Make an I-Spy board by gluing all sorts of objects to a poster board. Then take turns calling out items for the other person to find and touch.</li><li>Flip over all the pieces of a puzzle and try to put it together without looking at the picture. Start with a small puzzle.</li><li>Find a hill to roll down.</li><li>Blow up one more balloon than you have people and try to keep them all off the ground.</li><li>Practice whistling.</li><li>Dye eggs even if it&#39;s not Easter.</li><li>Draw a bath for your grandchild and put in lots of toys that aren&#39;t bath toys, anything that won&#39;t be hurt by the water.</li><li>Teach your grandchild yoga poses like the lotus and the tree. Then make up your own pose and give it a name.</li><li>Find some water and throw rocks into it.</li><li>Mark off a section of your yard or garden and count the living creatures you can find in it.</li><li>Have a pet show with stuffed animals and give one first prize.</li><li>Go for a walk or hike at night. Be sure to take flashlights.</li><li>Time your grandchild doing something, like climbing a play structure or running around the house, and record his or her personal best for next time.</li><li>Have a tea party and make up funny names for the tea and treats.</li><li>Make mud pies.</li><li>Give each other silly names for a day, and see who does the best job of sticking to the silly names.</li><li>Find an old deck of playing cards and cut slits in the sides, then use them to build crazy structures.</li><li>Have a backwards day. Put your clothing on backyards and see how many things you can do in reverse.</li><li>Find some worn or stained items of clothing and cut them up to create some funky new items.</li><li>Teach the grandchildren to wiggle their ears. (Hint: Put on a pair of glasses even if you don&#39;t wear them. Lean the head forward until you can feel the weight of the glasses on your ears. Then use the ears to pull the glasses back. That&#39;s the movement involved in wiggling the ears.)</li><li>Pound nails into a board.</li><li>Make a paper doll chain.</li><li>Dig a hole.</li><li>Make a blanket fort.</li><li>Make newspaper hats.</li><li>Have a picnic on a blanket in the back yard.</li><li>Have a Happy Unbirthday party with odds and ends of leftover party goods. Do make the cupcakes fresh, though.</li><li>Have a scavenger hunt that&#39;s limited to your own house. Give your grandchild a list of small items to find and a bucket or basket to carry them in. Make it more challenging by adding a time limit. If you have more than one grandchild on hand, turn it into a race.</li><li>Blindfold a grandchild and see how many smells he or she can identify.
