Hummingbirds love pink or red flowers. They guard their favorite flowers and try to keep other birds away. They fight one another for food. Their wings make a whirring sound when they hover over flowers to sip nectar. The tiny birds fly long distances to go to a warmer climate for the winter. They make their tiny nests in shrubs or trees.

Danger often appears in the most unexpected places. People usually think of the bathtub as a safe, quiet place. But more accidents occur there than anywhere else in the home. Slips or falls that occur while entering and leaving the tub injure thousands of people every year. Most people think of a baker as having a safe and pleasant job; however, rolling, kneading, and pounding dough causes clouds of flour dust, which can enter the lungs and disable the baker.

When it comes to making ice-cream, you can do it the traditional way, by stirring it in a frozen container, or you can use liquid nitrogen to freeze your mixture. There are some advantages to using liquid nitrogen. Since liquid nitrogen freezes the mixture faster, the crystal grains are smaller, giving the ice-cream a creamier texture. The downside is that ice-crystals grow faster in ice-cream prepared using liquid nitrogen, so it must be stored at much colder temperatures. Both methods produce a distinct texture, and both are delicious.

It was the most beautiful banana split that I had ever seen. In the middle of the bowl, there were three scoops of ice-cream: chocolate, strawberry, and vanilla. On top of the ice-cream were a banana and a thick web of chocolate and caramel sauces. A huge puff of whipped cream covered the sauces and a handful of crushed nuts dappled the whipped cream. On top of it all was a cherry, but I’ve never liked the soggy squish of cherries. 

One time my mom and I made ice-cream. We added sugar and cream into a big glass bowl. We kept it frozen in the middle of a bigger glass bowl. While it froze, I stirred the mixture with a hand mixer. It was the first time that had I used one and it splattered ice-cream mixture all over the kitchen. The rest of the mixture finally froze, so we ate some ice cream, and then put the remaining portions in the freezer so that it wouldn’t get freezer burned. That was a good day. 

Have you ever had an ice-cream headache? That’s when a painful sensation resonates in your head after eating something cold (usually ice-cream) on a hot day. This pain is produced by the dilation of a nerve center in the roof of your mouth. The nerve center is overreacting to the cold by trying to heat your brain. Ice-cream headaches have turned many smiles to frowns. 

Making ice-cream is not easy. Cream and sugar have to first be mixed in a frozen container. Ingredients may be added at this point, if desired. The mixture must be stirred and whipped until the cream and sugar mixture is frozen. Depending on the equipment, this may take as long as an hour. After the ice-cream is prepared, it must be kept frozen until it is ready to be enjoyed. Making ice-cream is difficult, but most people would agree that it is worth the trouble. 

No one knows the true origin of ice-cream, but the first published ice-cream recipe appears in “Mrs. Mary Eales's Receipts,” a cookbook that was printed in London in 1718. Sometime around 1832, an African-American confectioner named Augustus Jackson created multiple ice cream recipes and invented a superior technique to manufacture ice cream. Ice cream soda was invented around 1874, but the real breakthrough may have been at the 1904 World’s Fair in St. Louis, Missouri when the American ice-cream cone was unveiled! 

Freezer burn may have wasted more ice-cream than sidewalks. If you don’t know, freezer burn is when ice crystals form on the surface of ice-cream. These ice crystals can ruin the texture and flavor of the ice cream. But you can prevent freezer burn. Since freezer burn is caused when melted ice-cream is refrozen, rather than eating your ice-cream from the container as it melts, scoop your ice-cream into a bowl and put the container back in the fridge immediately. Doing this ought to help you solve your issues with freezer burn. 

The ice-cream shop around the corner from my house has the best ice-cream in the city. When you first walk inside, there is a long chrome counter with matching stools extending to alongside the far wall. Right where the counter stops, the booth seating begins. There are lots of old-timey knickknacks on the walls and chrome napkin holders on all the tables. My favorite part of the shop is behind the counter glass, where they keep all of the ice-cream flavors. A rainbow of delicious sugary flavors is kept cool and delicious behind the counter glass. 

Ice-cream is a delicious frozen treat that comes in a many different colors and flavors. Two of my favorite flavors are strawberry and chocolate. Though both of these flavors are delicious, strawberry may contain pieces of fruit while chocolate usually will not. Even though more chocolate ice-cream is sold across the country annually than strawberry, each flavor tastes great inside of a milk shake.
