Bottled memory

If I had one memory to bottle up and open it up anytime it would be the time me and my great grandpa went to a science park. It took place when I was 7 years old and I was in love with anything that had to do with science making it a really happy  memory. II will open it oftenly because my great grandpa died 3-4 years ago and this was the happiest memory we had. The time I will uncorked it , it would feel I was seven again with him
